The story behind Blood Pressure

Low blood pressure happens when the blood flow to the brain and other vital organs falls short, due to low pressure in the blood. Some common causes of low blood pressure are dehydration, heavy meal, severe infection, heart attack, heart failure or pregnancy. You will notice some common sign and symptoms like dizziness, lack of concentration, nausea, blurred vision and many more.

- Home Remedies for Low Blood Pressure

* Drink as much water as you can. Dehydration minimizes the blood volume which causes the drop in pressure. Drink one glass of water per hour; this would help to keep your body hydrated.

* Keep your knees flexed as this helps in bringing the pressure back to normal.

* As you warm-up before exercising it is very important to cool down after exercising. Stopping in the middle of an exercise routine can drop your pressure, so avoid it.

* Drinking alcoholic beverages does not help the low blood pressure condition. Drink healthy juices or any non-alcoholic drinks which can make your life healthy and lot less complicated.

* Salt is good for low blood pressure. You can increase your salt intake, but this increase in salt may vary from person to person.

* While sleeping keep your head elevated as this may help to adapt to an upright position.

* Be health conscious and do stretching exercises which helps to keep a tab on the pressure level. You can squeeze your fists and pump your stomach a few times to help this problem.

* A larger meal causes the blood to rush towards the digestive area leading to insufficient supply of blood to other organs. Emphasis on smaller meals, as this would help to provide proper flow of blood in the entire body.

* Take a walk after your meals. This helps in bringing the blood pressure level to normal.

* Ginseng is a Chinese root, even though its benefits are still unclear, it has been said that it helps in improving low blood pressure.

* Soak 10 small raisins in bowl of water overnight. Chew each raisin at least 30 times before swallowing it. Continue doing this for a month.

* Soak 5 pieces of almond in water and keep it overnight. Grind them to make a smooth paste and mix it in glass of milk. Boil the almond and milk paste. Drink it warm.

What is Feline Diabetes

Believed to effect 1 in 400 cats, feline diabetes often presents itself with symptoms that are very similar to those found in humans. The good news is that feline diabetes is treatable and does not necessarily mean a shorter life span or lesser quality of life for cats. In many cases, early and effective treatment of feline diabetes may even lead to a complete remission, which means that a cat will not continue to need insulin injections.

Early detection of feline diabetes is critical to a cat's health. If left untreated, this illness can lead to weakness in the legs, malnutrition, dehydration and possibly even death. The symptoms of feline diabetes are gradual and may manifest themselves over a period of several weeks. Typically, feline diabetes if not found in cats that are under 7 years of age. The first signs are likely to be a sudden weight loss or gain. In addition, excessive drinking and urination may be accompanied by an sudden increase in, or loss of, appetite. The next symptom of feline diabetes may be the back legs growing increasingly weak.

Once any of the aforementioned signs begin to surface, it's time to take your pet to the veterinarian for the appropriate tests. If feline diabetes is confirmed, one of the most important treatment methods will be that of a well-balanced diet. Based upon your cat's needs, the veterinarian will recommend a diet and nutrition plan, which can be utilized in addition to regular insulin injections. Oral medications are also often prescribed in place of injections, but pills are often thought to cause liver damage or possibly even a remission reversal in cats. Therefore, most pet owners opt for insulin injections for the most effective treatment of feline diabetes.

While in treatment, it is important that cats be taken to the veterinarian for regular checkups and to monitor their health and dietary habits. If this illness is not treated properly or if their diet is not closely monitored, your pet may end up hospitalized. When dealing with feline diabetes, there is no room for error and pets must be closely supervised to make sure that they are eating right and gradually beginning to regain their strength.

The information in this article is intended for informational purposes only. It should not be considered as, or used in place of, medical advice or professional recommendations for the diagnosis or treatment of feline diabetes. If necessary, individuals should take their pet to a licensed veterinarian for further information regarding feline diabetes, including a proper diagnosis and treatment.

Methods to reduce Acne

Acne gives the combination of symptoms like greasy skin, white heads, black heads, pimples, inflammation and scar formation. Acne mostly affects young people in the age 14 - 25, but also sometimes older persons, like women in their menopause. Most teenagers experience outburst of acne, some only little, but for others acne may develop into a serious skin ailment with great cosmetic impact.

THE SKIN ANATOMY

To understand the acne process, some knowledge about skin anatomy and physiology is essential:

The skin has there layers: The outer layer called epidermis consists of epithelial cells. Under this lies the dermis consisting of connective tissue. At the bottom there is a layer called the hypodermis consisting mostly of fat cells.

The skin has narrow pores extending from the surface down to the top of the sub-dermis, called hair follicles. A hair extend from a growth zone in the bottom of each hair follicle and out at the skin surface. Around the hair in the dermis, there are small glands called sebaceous glands. These glands produce a fatty substance, sebum, which empty through the follicle opening and lubricates the hair and the skin.

THE ACNE PROCESS

Acne starts by the glands in the hair follicles increasing their sebum production. This will in the beginning only cause greasy skin. Eventually the sebum in the entrance of the follicles mixes with dead epithelial cells. This mix reacts chemically to forms hard props, comedones that close the pore entrances. According to the color of the comedones, they are called black heads or white heads.

Then the closed hair follicle gets filled with sebum and swell. The swollen follicle then gets infected by bacteria. The bacteria and the accumulated sebum cause the follicle and the surrounding skin to get inflamed, forming a pimple. At last the inflamed follicle burst and empties its content. Eventually the affected area heals. Sometimes the inflammation reaches deep into the skin surrounding the follicle and destroys skin tissue. This will cause more or less distinct scars that may reside permanently. Typically an affected person will have follicles in all these stages of the process at any given time.

THE CAUSES OF ACNE

The increased hormone production in the puberty stimulates to increased sebum production. The male hormone, testosterone, seem to contribute most. Also girls begin to produce more testosterone in the puberty. Also in other periods, altered hormone production may give acne, for example by women in the menopause.

Since not all teens get acne in any degree, the increased hormone level cannot be the whole cause of the increased sebum production. The follicles of affected persons must for some reason react stronger upon the higher hormone level.

Dietary factors, like eating too much fat, too much sugar or the wrong kind of fat may aggravate acne by some individuals. Lack of vitamins, minerals and essential fatty acids may also contribute to development of acne.

Poor digestion, lazy colon and constipation aggravate acne in some individuals, probably due to productions of toxins in the intestines. Lazy colon may be caused by dietary faults, like lack of fiber.

Very frequent washing and use of strong soaps aggravate acne, and does not alleviate the condition as many think. Rubbing, scrubbing or squeezing the skin may also aggravate acne.

Here are some other factors that may contribute in causing acne or aggravating the condition.

- Stress - Some contraceptive agents - Environmental or domestic pollution. - Humid environments. - Some antidepressants. - Testosterone and anabolic steroids used for treatment or by body-building. - Use of some types of greasy cosmetic products. - Some antiperspirant products. - Exposing the skin for chlorine or other halogens, or medicines containing halogens. - Women may get aggravated acne 2-7 days before menstruation.

WHAT CAN YOU DO YOURSELF TO AVOID OR TO TREAT ACNE

Sometimes Acne is so severe that special medical treatment is required, and sometimes the causes of acne necessitate medical treatment. But you can do much yourself also. Here are listed things you can do yourself to prevent or treat acne:

1. Some advices about diet that may help prevent and cure acne:

- Do not consume a great amount of fat. - The fat you add to the food should be natural oils. Olive oil is ideal, but use other types of oils too, like walnut oil, sunflower oil and soy oil. However, do not use only soy oil as many tend to do. Using only soy oil will give you too much of some fatty acids and too less of others. - Eat much fish, seafood and not so much meat. - Eat food with a high fiber content to regulate the digestion, like vegetables, whole cereals, full corn bread and fruit.

2. Here are some things you should avoid.

- Do not use greasy or heavy cosmetics that clog your skin and are difficult to wash away. - Do not use strong irritating antiperspirants. - Do not wash with strong soap or cleaners that dry up your skin and take away all the natural oily protection in your skin. - If you perform body-building, do not use anabolic steroids or other hormonal supplements. - Use clothes that allow air to reach your body surface to avoid collection of humidity and overheating of your skin.

3. Use of rinsing milk or solutions

You can rinse your skin with mild products especially made to dissolve the plugs in your pores, and to make the environment in your skin unfriendly to bacteria causing infection. Some of these products are just products to wash your skin with one ore more times a day; others should be on during night and flushed away in the morning.

Salicylic acid is a mild ingredient often used in these products to dissolve the comedones. The products usually also contain ingredients that work antibacterial and stimulate the skin's own cleaning activities, like Tea tree oil or Echinacea extract.

4. Use of gels and creams to treat acne and protect your skin

After the rinsing, you should apply some treatment gel, cream or lotion onto your skin to achieve these effects:

- To make your skin soft and elastic. - To protect your skin against the environment. - To acts further to dissolve the clogging of your pores. - To soothe and alleviate inflammation. - To kill the bacteria causing infection or make an environment hostile for the bacteria. - To stimulate the skin to clean itself. - To stimulate the skin to heal. - To be used as a isolating layer between the skin itself and cosmetics

In order to protect, make the skin soft and further dissolve the comedones, many products contain natural plant oils that are easily absorbed into the epidermis, like Tea tree oil, Rose hip oil, Lavender oil and Olive oil.

Ingredients used in products to reduce inflammation and to stimulate healing may be: Aloe Vera extract, Viola Tricolour extract, Rose hip oil, Vitamin E and Vitamin A.

Tea tree oil and Grapefruit seed extract are natural antibacterial agents used in many of these products. In other products artificial compounds like Benzoyl peroxide are used.

5. Oral supplements to fight the acne process and nourish the skin

Supplements taken by mouth to nourish your skin may be useful. The purpose of these supplements is more or less the same as that of nourishing creams.

- To make the sebum more fluid so it drains more easily. - To stimulate the substance exchange and cleaning processes in your skin, - To stimulate your skin to heal, - To give your skin building nutrients necessary to heal.

Ingredients often used in these supplements to stimulate the cleaning and healing processes in the skin are: Vitamins A, C, B1, B2, B3, B6, C, D, E, Folic acid, Beta carotene, Bioflavonoids, Magnesium, Copper, Zinc, selenium, anti-oxidants from Green tea, Metylsulfonyl methane.

Nutrient found in these products used as material to rebuild damaged skin and to give a sebum with better consistency are: Evening primrose oil, Olive oil, Flax seed oil, Borage oil, Soy oil, Wheat germ oil and Lecithin.

Gum guggul extract used in oral products has an anti-biotic effect, and helps against spreading of the acne infection and thus helps against scar formation.

The effect of Alcohol on Diabetes

Drinking Alcohol Really Does Decreases the Risk of Type 2 Diabetes Among Older Women It is absurd. For the longest time, we have believed that alcohol has no real benefits. However, recently, a study has found that drinking moderate amounts of alcohol really does decreases the risk of Type 2 Diabetes, and this is especially true among Older Women! There are 20.8 million children and adults in the United States, or 7% of the population, who have diabetes. While an estimated 14.6 million have been diagnosed with diabetes, unfortunately, 6.2 million people (or nearly one-third) are unaware that they have the disease.

Recent studies have shown that drinking moderate amounts of alcohol (as compared to drinking too much alcohol or no alcohol at all) can lower the chances of getting type 2 diabetes. However, only a few studies on alcohol and type 2 diabetes have included women, and very few have included older women.

Previous studies on the effects of drinking moderate amounts of alcohol (1-2 drinks) and the risk of developing type 2 diabetes have mostly been done on men or both men and women who were younger than 55 years old. The researchers wanted to study how drinking alcohol affects older women's (more than 50 years old) chances of developing type 2 diabetes. (see Diabetes Symptoms)

Questionnaires were mailed to the women in the study. The women were asked where they lived and if they had conditions that put them at risk for any other diseases. Waist and hip, height, weight, and blood pressure measurements were taken at the beginning of the study. Diabetes, high blood pressure, and high cholesterol were also reported if these conditions were diagnosed by a doctor. The questionnaire asked about how much each woman exercised and how much they ate.

The questionnaire also contained questions about how much alcohol the women drank, how often they drank, and what types of alcohol they drank, both currently and in the past. The researchers sent out two follow-up questionnaires every 3 to 5 years. These questionnaires asked the women whether they developed type 2 diabetes, what year they were diagnosed, who diagnosed them, and whether they were being treated by diet, drugs, and/or insulin.

Conclusion The researchers found that blood pressure was lower in the women who drank moderately, but it increased in women who drank more. During the study, a total of 760 new cases of diabetes were diagnosed. The research shows, however, that drinking alcohol in moderate amounts did lessen the risk of developing type 2 diabetes. This is rather significant piece of news as we can now safely drink our favourite wine and not feel guilty about it!

How to renew the skin from Acne

What is Accutane? Accutane is a form of vitamin A. It reduces the amount of oil released by oil glands in your skin, and helps your skin renew itself more quickly.

Accutane is used to treat severe nodular acne. It is usually given after other acne medicines or antibiotics have been tried without successful treatment of symptoms.

Accutane may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about Accutane? Accutane can cause severe, life-threatening birth defects if the mother takes the medication during pregnancy. Even one dose of Accutane can cause major birth defects of the baby's ears, eyes, face, skull, heart, and brain. Never use Accutane if you are pregnant. Women of child-bearing potential must agree in writing to use two specific forms of birth control and have regular pregnancy tests before, during, and after taking Accutane. Unless you have had a total hysterectomy or have been in menopause for at least a year, you are considered to be of child-bearing potential.

Accutane is available only under a special program called iPLEDGE. You must be registered in the program and sign agreements to use birth control and undergo pregnancy testing as required by the program. Read all program brochures and agreements carefully.

It is dangerous to try and purchase Accutane on the Internet or from vendors outside of the United States. The sale and distribution of Accutane outside of the iPLEDGE program violates the regulations of the U.S. Food and Drug Administration for the safe use of this medication.

What should I discuss with my healthcare provider before taking Accutane? Accutane is available only under a special program called iPLEDGE. You must be registered in the program and sign documents stating that you understand the dangers of this medication and that you agree to use birth control as required by the program. Read all of the iPLEDGE program brochures and agreements carefully. Ask your doctor or call the drug maker if you have questions about the program or the written requirements.

It is dangerous to try and purchase Accutane on the Internet or from vendors outside of the United States. The sale and distribution of Accutane outside of the iPLEDGE program violates the regulations of the U.S. Food and Drug Administration for the safe use of this medication.

Do not use this medication if you are allergic to Accutane or to parabens, or if you are pregnant or may become pregnant. Before taking Accutane, tell your doctor if you are allergic to any foods or drugs, or if you have:

Improvement In Cardiac CT Scanning

Answering a growing demand for radiation dose reduction in cardiac CT scanning, GE Healthcare announced the release of "SnapShot Pulse" at a national meeting earlier this month. This advancement in technology will achieve up to an 83% reduction in the patient's radiation exposure as well as improve image quality. Los Angeles CT Scan expert explains.

The average American's total radiation exposure has nearly doubled since 1980, largely because of CT scans. Medical radiation now accounts for more than half of the population's total exposure; it used to be just one-sixth, and the top source was the normal background rate in the environment, from things like radon in soil and cosmic energy from the sun. But CT use continues to soar. About 62 million scans were done in the U.S. last year, up from 3 million in 1980.

Los Angeles CT scans became popular because they offer a quick, relatively cheap and painless way to get 3D pictures so detailed they give an almost surgical view into the body. But they put out a lot of radiation. In a few decades, as many as 2 percent of all cancers in the United States might be due to radiation from CT scans given now, according to the authors of a recent report in the New England Journal of Medicine. A CT scan of the chest involves 10 to 15 millisieverts (a measure of dose) versus 0.01 to 0.15 for a regular chest X-ray, 3 for a mammogram and a mere 0.005 for a dental X-ray. The dose depends on the type of machine and the person - obese people require more radiation than slim ones - and the risk accumulates over a lifetime.

Cardiac CT scanning Los Angeles has, in the last few years, has been increasingly become part of the diagnostic armamentarium available to cardiologists in their quest for an early and accurate diagnosis of heart disease in selected patient populations. Radiation exposure from these studies is nonetheless significant, and should always be discussed with the patient in the context of risk versus benefit. Unnecessary tests should be cancelled, breast shields should be made use of, and the latest technology that permits diagnostic quality studies while minimizing radiation exposure necessary to produce them should be utilized. On this last note, GE's "SnapShot Pulse" is only the latest in what appears to be a continued effort by the industry to evolve the technology to minimize radiation exposure in the cardiac CT field.

The Missing Link Between Acne And Rosacea

There is growing evidence that the major cause of MRSA is the inappropriate over prescribing of antibiotics by general practitioners. This is not news and it is common knowledge that most infections are viral and do not require antibiotics.

Also it is well known that antibiotics upset gut bacteria and lead to overgrowth of the intestinal tract with fungi such as Candida which is present in everyone's guts, but normally kept in check by the probiotic bacteria surrounding it and which also produce chemicals to keep it in check. Antibiotic use can reduce the probiotic bacteria and allow the fungus to grow which over time can lead to inflammation and misdiagnosis of IBS later in life and open another chapter in prescribing. A downward spiral we don't want to promote. Candida overgrowth and dysbiotic guts probably affect millions of '20 something's' who have just had years of antibiotics for acne, or million of 40 something's who have been put on antibiotics for rosacea. We have clever ways of restoring the normal bacterial balance and reducing Candida without harsh antifungals.

However the use of antibiotics for skin infections such as acne and rosacea often at low doses and often for 3 to 6 months at a time is probably the biggest cause of MRSA (multi resistant Staphylococcus aureus) in hospitals. Let me explain.

It doesn't matter whether oral or cream antibiotics are used they cause the same problem. In acne if you have many blocked 'pores' (pilo sebaceous ducts) then the anaerobic bacteria propiobacterium acnes (p.acnes) can start to colonise the area under the plug and cause inflammation and damage. This bacterium only survives in normal skin at very low levels as it likes to live in an environment where there is little or no oxygen. When you create a blockage as with acne, you create the environment for p.acnes. So antibiotics can help to reduce p.acnes, but they also hit other friendly skin bacteria and herein lies the problem.

Staphylococcus epidermidis (s.epidermidis) lives on our skin and helps keep other nasty bacteria away. It likes an oxygen rich environment. The same antibiotics that reduce p.acnes often hit the s.epidermidis as well. This attack puts selective pressure on the bacteria to survive and within three or four weeks you can isolate resistant strains s.epidermidis on skin being treated with antibiotics.

Now Staphylococcus epidermidis is related to Staphylococcus aureus (s.aureus) (cousins if you like). S. aureus lives inside the body and s.epidermidis lives on the skin. They meet at places such as the nose and other entrances into the body. They can pass information to each other through the use of things called plasmids and it is highly likely information for developing resistance is transferred.

Hey presto we have started the super bug development. The acne sufferer ends up in hospital for an operation. They get a wound infection either from their own bacteria but also through other bugs already there. S.aureus is a typical bacterium that infects wounds. The antibiotics used for wound infections are often the same or similar to the one that has been used for the patient's acne, and it is not surprising they find the antibiotics don't work as the bugs are already resistant. This resistant strain becomes the dominant resident s.aureus in the hospital and is extremely difficult to remove and can go on to infect many other patients.

Using a product such as Aknicare which has 4 antibacterial agents which control p.acnes by changing conditions in the area under the plug rather than directly destroying it means you can prevent damage and inflammation without breeding resistant bugs. Aknicare can reduce p.acnes and all the other key causes of an acneic skin (inflammation, oil production, cell turnover) all without breeding resistant bugs.

As a final thought the main treatment for rosacea recommended on PRODIGY, the GP prescribing database recommends ROSEX creams and gels. Rosex contains the antibiotic metronidazole. Rosacea patients often use it for months and years. It works in a few. Metronidazole is also a powerful antioxidant and it is these properties that help with rosacea symptoms, not the antibiotic properties. Rosacea is not caused by bacteria. It is a sobering thought that the antibiotic most used in theatre to prevent infections during and shortly after surgery is metronidazole. Imagine if you had been using it for months or years before that operation.

It is concerning to think the antibiotic you are using today could end up leading to someone dying in hospital in the near future. Change prescribing habits for acne and rosacea now and have an impact on MRSA in hospitals.

Use Aknicare, a new medical device with a CE mark . Once in the drug tariff this should be prescribed by GPs. PCTs should act now
