Extremely Low Reading Of Thyroxine - What Does It Mean?

Extremely Low Reading Of Thyroxine - What Does It Mean?

Do you have an extremely low reading of thyroxine or T4, it means that you are suffering from an under active thyroid disease called hypothyroidism. With this condition, your thyroid glands fail to make sufficient thyroid hormones. The thyroid gland releases hormones, which travel all over your bloodstream and affect all parts of the body. Thyroid controls how the cells of the body use energy from food via the metabolism process, which in turn affects the body’s temperature, heartbeat and burning of calories. Lack of thyroid hormones slows down the body’s functions, reduces your energy and the metabolism is disrupted.

Causes of hypothyroidism:

The primary cause of this condition is Hashimoto’s thyroiditis. Thyroiditis refers to an inflammation of your thyroid gland. Hashimoto’s thyroiditis is an autoimmune disorder in which extra antibodies are produced which destroy the thyroid gland. Viral infections may also lead to thyroiditis.

Other causes of the condition are as follows:

  1. Radiation therapy to the neck region for the treatment of several cancers like lymphoma may damage the cells present in the thyroid gland. Hence, the gland cannot secrete hormones properly.
  2. Radioactive iodine treatment is undertaken by people having an overactive thyroid gland. Radiation destroys the thyroid gland cells and leads to hypothyroidism.
  3. Certain medicines used to treat heart problems, cancer and psychiatric diseases may affect the thyroid gland and lead to hypothyroidism.
  4. Surgeries undertaken for removing the thyroid also lead to hypothyroidism.
  5. Iodine is required by the thyroid gland to produce hormones. A low amount of iodine in your diet and body may lead to hypothyroidism.

Risks factors of hypothyroidism:

Usually women, especially older women are more likely to get hypothyroidism than men. The factors which determine if you are at a risk of acquiring the condition are as follows:

  1. Race
  2. Age
  3. Premature graying of hair
  4. Autoimmune disorders like type 1 diabetes, rheumatoid arthritisvitiligoceliac disease, Addison’s disease and many more.
  5. Bipolar disorder
  6. Turner’s syndrome
  7. Down’s syndrome

The symptoms of hypothyroidism are as follows:

  1. Changes in menstrual cycle
  2. Constipation
  3. Hair loss and dry hair
  4. Fatigue and tiredness
  5. A slow heart rate
  6. Depression
  7. An increased sensitivity towards cold
  8. Swelling of the thyroid gland or goiter
  9. Gaining weight unusually or great difficulty in losing weight
  10. Carpal tunnel syndrome

If you observe the symptoms of hypothyroidism, you should consult a doctor who will prescribe several blood tests, such as the thyroid stimulating hormone test and the T4 or thyroxine test. Based on the results, a treatment method is adopted.

Its related to thyroid. I had a recent blood test and found that the level of t3 is 3.03 and t4 is 15.00 and tsh is <0.015.the level of t3 and t4 is high. Looking forward to get some advice to improvise the increased level.

The normal range for t4 is 5 to 13.5 micrograms per deciliter—and t3 is also normal and there is no problem with your blood report and the low tsh indicates the need for thyroxine supplement.

Having some thyroid problem recently detected for that medicine thyroxine 25 (thyroxine I p) is being taken for the last one week. How long I should take the medicine?

You have to take the thyroxine supplement for lifelong as your thyroid gland is unable to produce the hormones for the smooth functioning of the body systems and we have to give the hormones as a supplement.

Hello doctors I did my thyroid test. My tt4 total is 11.5 and normal range is till 11.0.please suggest me something so that I can get of this thyroid 100%.totally out of my life. And also let me know what is tt4.

Hello lybrate-user. Either you can try yogasanas and pranayama to control it or you should start homoeopathic treatment to cure it. Allopathic treatment does not cure it. Instead it will keep increasing. You can consult me at Lybrate for homoeopathic treatment.

This is not the issue of medicine and thyroid medicine needs to be taken lifelong and you have not told if you have hypo or hyperthyroid, whatever the issue is you need medicines for lifetime and surgery in some cases.

Thyroid - Do You Still Have Chances Of Pregnancy?

Thyroid - Do You Still Have Chances Of Pregnancy?

Thyroid is a small, ‘butterfly shaped’ gland, situated just below the larynx (voice box) in the lower part of the neck, just above the collar bones.


What Is The Function Of Thyroid Gland?

The purpose of the thyroid gland is to take iodine from foods that we consume and convert them into thyroid hormones: thyroxine (T4) and triiodothyronine (T3).
T4 and T3 are responsible for the metabolism of every cell, proper growth, development and repair of the body. It is important for the development of the central nervous system, regulation of blood calcium levels, energy production, fat metabolism, oxygen utilization, and weight maintenance.

Causes

  1. Exposure to environmental toxins – electromagnetic radiation, chemicals, pesticides, heavy metals
  2. Genetic susceptibility
  3. High levels of stress
  4. Nutritional deficiencies
  5. Autoimmune disorders
  6. Infections
  7. Other hormone imbalances, e.g. estrogen, prolactin imbalance

How Does Thyroid Influence Fertility Potential?

Thyroid problems can interrupt the complex process of the menstrual cycle and can result in an irregular menstrual cycle. This, in turn, results in failure of fertilization of an egg by the sperm and thus, failure in conception.

  1. Anovulatory cycles: This means that you are not ovulating i.e. not releasing an egg.  Luteinizing Hormone (LH) is responsible for the release of an egg from the ovary. If thyroid hormone levels are imbalanced, they cannot support LH to do this.  If no egg is released this makes pregnancy impossible.
  2. Luteal Phase Problems: It takes around 13-15 days to nurture a fertilized egg. If the second half of your menstrual cycle (luteal phase) is very short due to poor LH response and subsequent insufficient progesterone production (T3 required for progesterone release from the luteal cells), a fertilized egg can’t implant securely and will end up leaving your body at around the same time when menstruation would occur.
  3. Low Body Temperature: Low thyroid function will also cause a lower basal body temperature. The rapidly dividing cells in a little embryo need a specific temperature range for that division to take place.  If your basal body temperature is very low, the embryo may not be able to continue growing. This increases the risk of early miscarriage.

How can you still be Pregnant?

Increased intake of iodine-rich food: Whole fat yogurt, raw dairy product, strawberries, potatoes with the skin left on, zinc with vitamins E, A, B, C, and selenium are responsible for thyroid hormone manufacture.
Stress results in elevated levels of cortisol. Increased cortisol level will inhibit the conversion of T4 to the active T3 hormone and will stop the active T3 entering cells sufficiently. Stress Management techniques like meditation, Yoga is required.

Exercise is beneficial as it will stimulate thyroid hormone secretion and increase tissue sensitivity to thyroid hormones.

You have hypothyroidism which means the reduced thyroid hormone thyroxine is produced by the thyroid gland and this thyroxine is needed for almost all metabolic functions of the body and absence of it can cause many diseases. You have to thyroxine supplement eltroxin 100 mcg to start with and check again after a month.

The normal range of TSH levels is 0.4 to 4.0 milli-international units per litre. You have hypothyroidism and it can occur in young age and need medication
