Low Thyroid

Low thyroid, also known as hypothyroidism, is a condition where the thyroid gland is under active. This means that the thyroid gland is producing insufficient supply of thyroid hormones. As a result, one may feel general weakness as the body tends to become slow. This is because the low thyroid activity affects the body cells causing a sudden slow down and other undesirable symptoms.

The low thyroid condition can be classified into three- primary, secondary and tertiary. Primary hyperthyroidism is characterized by the thyroid’s reduced production of thyroxine and triiodothyronine hormones. On the other hand, secondary hyperthyroidism occurs with a damaged pituitary gland, leading the thyroid to produce low levels of hormones. Finally, tertiary hyperthyroidism can be traced from the hypothalamus dysfunction causing the pituitary and the thyroid not to perform their functions as well.

Low Thyroid symptoms and treatment

The low thyroid symptoms are usually not easily recognized. This is because they can mimic other condition’s symptoms. For mild patients, symptoms may not be observed. The symptoms then will become obvious when the condition worsens. Common low thyroid symptoms include weight gain, fatigue, cold intolerance, dry hair and skin, loss of concentration and depression.

Treatment for low thyroid is also available through thyroid hormone replacement. There are synthetic T4 drugs available in the market that aims to help patients in their low thyroid treatment. Average dose of T4 drugs for adults is said to be approximately 100 to 150 micrograms per day.

Anti-Thyroid Drugs

What do antithyroid drugs do?

Antithyroid drugs block pathways leading to thyroid hormone production.

Antithyroid drugs used in this country are Propylthiouracil (PTU) and Tapazole®. Some physicians will recommend antithyroid medication as a first line of treatment to see if the patient is one of the lucky 30% of patients who go into a remission after taking antithyroid medication for one to two years. (Patients are said to be in remission if their hyperthyroidism does not recur after discontinuing the antithyroid drugs.) If antithyroid drugs do not work for the patient, then physicians usually recommend radioactive iodine.

Antithyroid drugs are also used to treat very young children, older patients with heart conditions, and pregnant women. For severe or complicated cases of hyperthyroidism, especially in older patients, PTU or Tapazole® can be given for four to six weeks to bring the hyperthyroidism under better control prior to administering radioactive iodine treatment.

In cases when women are diagnosed with Graves’ disease while they are pregnant, PTU is prescribed. The smallest dose possible is given because the medication does cross over to the fetus. The mother should be checked every three to four weeks during the pregnancy so that the lowest possible dose can be given. Too much PTU can cause fetal goiter, hypothyroidism, and mental retardation.

Are there any side effects?

Antithyroid drugs cause side effects in about 10% of patients. Reactions can include:

  • skin rash
  • swollen, stiff, painful joints
  • sore throat and fever
  • low white blood count, which can lead to serious infections
  • jaundice (yellow coloring of the skin) and, rarely, liver failure.

Most side effects clear up once the drugs are stopped. If you think you are having a reaction to anti-thyroid drugs, call your doctor immediately.

What can be expected with antithyroid drug treatment?

  • Several pills are taken from one to four times a day, every day for six to 24 months.
  • Some patients complain that the pills have an unpleasant smell and taste.
  • There is usually some symptom relief within one to two weeks. In some cases, it can take several months to relieve symptoms.
  • Antithyroid drugs have a relatively low success rate. While PTU or Tapazole® may correct the problem temporarily or for a few years, the chances of a permanent remission are about 30% once the drugs are stopped.
  • The likelihood of achieving a permanent remission is increased if the patient takes the medication for one to two years.
  • There are side effects in 10% of the people treated with Tapazole® or PTU. These are:
    • skin rash over most of the body swollen, stiff, painful joints
    • sore throat and fever — if this happens, the antithyroid drugs should be stopped immediately and the physician contacted
    • jaundice
    • liver damage, which is fatal in rare cases
  • Because antithyroid drugs pass into breast milk, only PTU in a dosage less than 200 mg a day is advised if the baby is not weaned.
  • Within 15 years, the thyroid gland may burn out, resulting in hypothyroidism, and the patient will need thyroid hormone replacement.

Beta-Blocking Drugs

When are beta-blocking drugs used?

Beta-blocking drugs, also called beta blockers, treat the symptoms of hyperthyroidism. They do not significantly affect the gland or the levels of thyroid hormones in the blood. Instead, they “block” the effects of thyroid hormones.

Beta blockers are most useful for patients whose hyperthyroidism makes them uncomfortable. High hormone levels can cause a faster heart rate and trembling. Beta-blocking drugs help control these symptoms.

Beta-blocking drugs should not be used by patients with asthma.

Thyroid Hormone Pills

When are thyroid hormone pills used?

Thyroid hormone pills provide the body with the right amount of thyroid hormone when the gland is not able to produce enough by itself. The pills are frequently needed after surgery or radioactive iodine therapy.

Thyroid hormone tablets are the standard treatment for hypothyroidism. While symptoms usually get better within a few months, most patients must take the pills for the rest of their lives. This is especially true for hypothyroidism caused by Hashimoto’s thyroiditis or radioactive iodine treatment.

If the entire thyroid gland has been surgically removed, thyroid hormone tablets replace the body’s own source of the hormone. If only a part of the gland has been removed, the pills may keep the remaining gland from working too hard. This decreases the chance that the thyroid gland will grow back.

How much hormone do I need?

The preferred hormone for treatment is levothyroxine (T4). You should use only the brand-name that your doctor prescribes, since generic brands may not be as reliable. Name-brand levothyroxine pills include Synthroid®, Levoxyl®, Levothroid®, Euthyrox®, and Eltroxin®.

Patients sometimes take more pills than they should, trying to speed up the treatment or lose weight. However, this can lead to hyperthyroidism and long term complications, such as osteoporosis. You should take the pills as your doctor prescribes.

At different times in your life, you may need to take different amounts of thyroid hormone. Therefore, you should see your doctor at least once a year to make sure everything is all right.

What to eat?

Healthy living with proper diet is essential to patients with low thyroid. Organic foods that help enhance the thyroid can be considered as low thyroid natural remedies. For example, increasing one’s iodine intake is helpful for patients. Foods like vegetables and fruits have iodine content in it. Other food sources include yogurt, eggs, fish, potatoes, parsley and banana.

Another important element in the body for low thyroid is selenium. Selenium is an element required by the body to help convert T4 hormone into a T3 hormone. With this, selenium supplementation is necessary. In addition, the amino acid tyrosine is also one natural wonder for low thyroid problems. Tyrosine is needed by the body in manufacturing thyroid hormones from the iodine content of the food. With this, tyrosine dietary supplements can be taken.

What Now?

Just like any disorder, low thyroid should be treated immediately to avoid further health problems. Consult a physician for some professional advice.
