About Hypothyroidism – a Common Health Problem

By hypothyroidism, the thyroid gland is producing too less hormones to stimulate the metabolism or the body is not able to utilize the hormones. The lack of thyroid hormones slows down the metabolism and thus all the activities in the body, giving a combination of many symptoms related to slowness of bodily processes.

Hypothyroidism is common, but the frequency of the condition is not well determined. Some authorities estimate that 0.5% of the total American population have the disease to some degree. The frequency is much greater among people over 50 years of age than among young people.


THE SYMPTOMS AND COMPLICATIONS OF HYPOTHYROIDISM

The most common early symptoms are: Mental and physical fatigue, weakness, weight gain or over-weight, and depression.

One or more of these symptoms also use to appear early: Constipation, sensitivity to coldness, cold hands and feet, thick tongue, decreased sweating, dry hair, thin brittle hair, thin brittle nails, muscle and joint pain, pale or yellowish skin.

One or more of these symptoms usually appear later: Poor memory, slow thought process, drowsiness, slow speech, thinning of eyebrows, hoarseness, poor circulation, dry and flaky skin, decreased taste and smell, menstrual irregularities, skin thickening, puffy face, puffy hands and feet, swelling of extremities, overall swelling, muscle spasms, muscle atrophy, joint stiffness.

In children or young persons hypothyroidism may give developmental problems, like disturbed tooth development and short stature.

Hypothyroidism increases the risk of elevated cholesterol levels, heart disease and diabetes (diabetes mellitus). This occurs even by moderately decreased thyroid production.


THE THYROID GLAND AND ITS HORMONES

To understand the hypothyroidism, some knowledge about the thyroid gland and its hormones is essential.

The thyroid gland produces hormones that accelerate and in other wise regulate metabolism. A part of metabolism is the process of breaking down energy containing nutrients, and using the energy to produce molecules that all the processes and activities in the body use as fuel. Another part is the production of molecules that the body use as building materials.

The thyroid makes four hormones: Thyroxin (T4), triiodothyronine (T3), diiodothyronine (T2) and monoiodothyronine (T1). The hormones contain iodine, and the figures tell about the number of iodine atoms in each hormone molecule. T3 is not made directly, but is produced from T4. T3 is a more efficient hormone than T4. Therefore this conversion is important.

The pituitary, a gland under the brain, produces a hormone called thyrotropin or thyroid stimulating hormone (TSH) that enhances the activity of the thyroid gland. If the body has too less thyroid hormone in the blood, the pituitary produces more thyrotropin. This makes the thyroid gland speed up its own production. By a too heavy thyroid hormone concentration, less thyrotropin is produced by the pituitary, and the thyroid gland slows down. This feed-back mechanism regulates the metabolism of the whole body.


THE MECHANISMS AND CAUSES OF HYPOTHYROIDISM

By hypothyroidism the body does not get enough thyroid hormone, or the hormones do not work effectively in the body. This causes the metabolism to slow down. When the metabolism decreases, the processes in the body do not get enough fuel and building materials, and all the body activities will therefore slow down. Energy containing nutrient will also be stored as fat, since they are not broken down.

Serious variants of hypothyroidism are called myxedema. This is a rare condition. However, less serious, but painful variants are common. There are several reasons for hypothyroidism, each giving a variant of the disease:

*An autoimmune reaction against the thyroid tissue can destroy the capability of the thyroid gland to produce hormones (for example Hashimoto's disease).

*Sometimes the production of T3 by conversion from T4 is impaired. The total amount of hormones may be normal in these cases, but the body is still lacking T3, and gets the symptoms of hypothyroidism.

*Iodine deficiency can cause hypothyroidism, since the thyroid hormones contain iodine. In Europe and America the food is seldom short in iodine, but bad nutrition may result in iodine deficiency.

*Surgery or radiation at the thyroid area can destroy enough tissue to cause hypothyroidism.

*Injury or disease in the pituitary or of the part of the brain controlling the pituitary may cause a decrease in secreted thyrotropin, and then the thyroid will respond by producing less of its own hormones with hypothyroidism as a result.

*Some people have symptoms of hypothyroidism even though the amount of thyroid hormone in the blood is normal. One of the symptoms is raised levels of thyrotropin, indicating that the body signals need for more thyroid hormones. This variant may be caused by conditions elsewhere in the body that make it difficult for the hormone to reach their destination in the cells. In many of these cases the immune system produces anti-bodies against the thyroid hormones. This variant is called sub-clinical hypothyroidism, and responds to the same treatment as ordinary hypothyroidism.

*Some types of food can contribute to a depressed thyroid function or aggravate hypothyroidism when eaten raw in great amounts: Brussel sprouts, broccoli, corn oil, cabbage, cauliflower, kale, kohlrabi, radishes, rutabaga, soy and turnips. By cooking these vegetables, the depressing effect is decreased.
*Factors suspected for causing hypothyroidism are: The artificial sweetener aspartame, mercury pollution, dental fillings containing mercury, fluoride and heavy metal pollution.


HOW CAN HYPOTHYROIDISM BE TREATED

For serious hypothyroidism caused by tissue destruction, external supplement of thyroid hormones is necessary.

When the condition is caused by lack of iodine in the diet, dietary changes and iodine supplements will be a part of the treatment.

Less serious, but painful hypothyroidism is sometimes also treated with hormone supplements. In these cases it is difficult to find the right dose, and treatment may result in hormone poisoning.

You can sometimes alleviate hypothyroidism by reducing the amount of food suspected for depressing the thyroid function: Brussel sprouts, broccoli, corn oil, cabbage, cauliflower, kale, kohlrabi, radishes, rutabaga, soy, soy products and turnips. However, these food types are valuable in many ways, so it is probably not wise to cut them out totally. Also try to avoid artificial ingredients like the sweetener aspartame, conserving additives and fluoride.

Changing out mercury dental fillings and avoiding mercury or heavy metal exposure may help to ameliorate the condition.

You may also alleviate the condition by eating food that stimulates the thyroid function according to practical experience: Chia seed, dulse, fish from the ocean, flax seed, pumpkin seed, seaweed, coconut and brewer yeast.

You can find nutritional supplements to help for hypothyroidism. The compositions of these products vary:

*They may contain building materials that the thyroid uses to make its hormones, for example: iodine, acetyl-L-tyrosine or L-phenylalanine.

*They may also contain vitamins and minerals that stimulate the mechanism of hormone production by being a part of necessary enzymes, or by helping the absorption of the ingredients that hormones are made from, like: Magnesium, zinc, selenium, copper and vitamin E.

*They may furthermore contain constituents that stimulate tissue regeneration by being part of tissue building enzymes, and thus helping to restore a degraded thyroid, for example: Folic acid or folate, vitamin B2 (riboflavin), B3 (niacin), B5 (pantothenic acid or pantothenate), B6 (pyridoxine), B12 (cyanocobalamin) and molybdenum.

About Acne - What can you do to cure or alleviate 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.
