Symptoms of high TSH levels

• Depression.
• Fatigue.
• Slow heart rate.
• Puffiness in the face.
• Cold intolerance.
• Weight and appetite changes.
• Hair loss and thinning.
• Constipation.

A low level of thyroxine and high level of TSH indicate an underactive thyroid. That’s because your pituitary produces more TSH in an effort to stimulate your thyroid gland into producing more thyroid hormone.

If your TSH level is higher than it should be, you may have hypothyroidism. This occurs when the pituitary gland overcompensates for low amounts of thyroid hormone by pumping out more TSH. This condition is most common in older women, but it can occur in any gender at any age.

Treatment

1. Radioactive iodine to slow down your thyroid.
2. Anti-thyroid medications to prevent it from overproducing hormones.
3. Beta blockers to reduce a rapid heart rate caused by high thyroid levels.
4. Surgery to remove the thyroid (this is less common)

According to Cappola, her research regarded mildly elevated TSH levels as those in the 4.5 to 7 mU/L range, while very elevated TSH levels were considered to be those greater than 20 mU/L.

Subclinical hypothyroidism is defined as a thyroid stimulating hormone (TSH) level of 4.6 to 10 mIU/L. A normal TSH level is 0.4 to 4.0 and full-blown hypothyroidism is 10 or higher.

If your TSH level is elevated to between 4.5 and 10 mIU/L and your T4 is normal, you should be considered for treatment with thyroid medication, especially if you have symptoms of hypothyroidism, or you have a positive test for thyroid antibodies, a history of heart disease, or risk factors for atherosclerosis.

TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.

Some research has found inflammatory cytokines, which are released into the body during a stress response, can reduce levels of thyroid-stimulating hormone (TSH). When you have a thyroid illness or imbalance, you’re more likely to have inflammation in the body, which can lead to other diseases and health problems.

Antioxidant-rich fruits and vegetables Blueberries, tomatoes, bell peppers, and other foods rich in antioxidants can improve overall health and benefit the thyroid gland. Eating foods high in B vitamins, like whole grains, may also help.

According to Dr. Kitahara, if someone has low thyroid function, their TSH is high, and the thyroid hormones known as T3 and T4 are low—and weight gain often occurs. If someone has an overactive thyroid or hyperthyroidism, TSH is usually low, the T3 and T4 are high, and weight loss occurs.

Low TSH levels indicate hyperthyroidism. This is also known as an overactive thyroid. If the thyroid gland is secreting levels of hormones that are too high, the pituitary gland produces less TSH. Symptoms of hyperthyroidism include: an irregular or rapid heartbeat.

Extremely low levels of thyroid hormone can cause a life-threatening condition called myxedema. Myxedema is the most severe form of hypothyroidism. A person with myxedema can lose consciousness or go into a coma. The condition can also cause the body temperature to drop very low, which can cause death.

A TSH level higher than 5.0 usually indicates an underactive thyroid (hypothyroidism) and a TSH level lower than 0.4 indicates the presence of excessive thyroid hormone and overactive thyroid (hyperthyroidism).

TSH helps regulate the levels of thyroid hormones in the body. In healthy people (with normally functioning thyroid glands), TSH should be to be about 0.4 to 5.0 µIU/mL. In people with thyroid cancer, TSH drops to 0.01 to 3.0 µIU/mL.

A suppressed serum TSH below 0.02mIU/L is less specific for hyperthyroidism in hospitalized individuals, compared with ambulatory patients. One study found that 14% of hospitalized patients with TSH <0.01 mIU/L were euthyroid.

A low TSH level—below 0.5 mU/l—indicates an overactive thyroid, also known as hyperthyroidism. This means your body is producing an excess amount of thyroid hormone.

Treatments for low TSH levels In many cases, doctors use radioactive iodine as a treatment for hyperthyroidism. This treatment destroys the thyroid gland over time, creating a life-long need for thyroid hormone medication.

Low TSH levels can mean your thyroid is making too much of the hormones, a condition called hyperthyroidism. A TSH test does not explain why TSH levels are too high or too low.

Hyperthyroidism typically does not go away on its own. Most people need treatment to make hyperthyroidism go away.

Severe and prolonged hypothyroidism and hyperthyroidism can cause loss of hair. The loss is diffuse and involves the entire scalp rather than discrete areas. The hair appears uniformly sparse. Regrowth is usual with successful treatment of the thyroid disorder, though it will take several months and may be incomplete.

Along with medication, there are different home remedies you may try to slow hair loss or regenerate hair growth.

1. Boost iron. Ferritin levels are associated with your iron stores.
2. Treat nutritional deficiencies.
3. Eat well.
4. Add anti-inflammatory foods.
5. Consider herbs.
6. Try essential oils.
7. Watch iodine intake.
8. Treat hair gently.

Thyroid disease: Abnormalities of the thyroid may also cause dizziness as a symptom. Hyperthyroidism (too much thyroid hormone) may cause palpitations, shortness of breath, and lightheadedness.

The neurologic disorders associated with thyroid dysfunction span the entire spectrum of neurology. Symptoms range from disorders of emotion and higher cognitive function to movement disorders, neuromuscular diseases, and a range of rarer yet significant neurologic sequelae.
