As with any hormonal disorder, the thyroid gland can be affected in two ways: it can produce too much thyroid hormone (hyperthyroidism) or too little (hypothyroidism). In this section, we focus on hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormones. When the thyroid gland is damaged due to illness or other factors, it leads to a gradual depletion of thyroid hormones, specifically T4 and T3. The condition in which the body lacks sufficient T4 and T3 is known as hypothyroidism and is often described as a sluggish thyroid. In more complex cases, evaluation by a Thyroid surgeon West Yorkshire may be recommended to determine the most appropriate treatment approach.

Why does a person develop Hypothyroidism?

There are many reasons why a person becomes hypothyroid. In Asian countries, one of the main reasons is a lack of iodine in the body, which is caused by a lack of iodine in the diet. Because of this, a person develops a goiter or vice versa. This is called iodine deficiency goiter.

Many people also become hypothyroid after they have had thyroid surgery (thyroidectomy) or after they have been given radioactive iodine (RAI). The thyroid gland can also be gradually destroyed by the body's own defenses (antibodies). This is called thyroiditis.

Medications can prevent the thyroid gland

Some medications can prevent the thyroid gland from producing enough T4 or T3. These include Amiodarone, PTU, Methimazole, and Lithium. Some diseases can lead to hypothyroidism, such as tumors of the thyroid glands (thyroid lymphoma) and tumors in the part of the brain called the pituitary and hypothalamus.

What are the symptoms and signs of Hypothyroidism?

The presence of symptoms of hypothyroidism is related to the duration of the disease and how severe it is. These include the following:

• Unintentional weight gain

• Fatigue or shortness of breath

• Difficulty in defecation or constipation

• Feeling cold or chilly easily

• Slowed thinking or forgetfulness

• Muscle aches

A doctor's examination may reveal the following:

• Slow heartbeat

• Dry skin

• Coarse or thin hair

• Goiter

• Swelling of the face and feet

Foods that can help to quickly normalize your thyroid hormone levels are those rich in iodine, such as marine fish and seaweed.

How to know if someone has Hypothyroidism?

A person who has the symptoms and signs mentioned above should be examined by an endocrinologist to determine if they are possibly due to hypothyroidism. The most important way to determine if a person is hypothyroid is to measure the level of TSH (thyroid-stimulating hormone) and T4 in the blood. This will show that the level of T4 from the thyroid gland is low while the TSH from the brain is high.

How is hypothyroidism treated?

The treatment of hypothyroidism is simple because only one medication needs to be given – levothyroxine. However, because the dosage required by each patient is different, it is necessary to return to the endocrinologist regularly to find out what dosage of the medication should be taken. The patient's feelings and the TSH results are used as a basis for changing the dosage. It is important to return to your doctor regularly because there are also negative effects of under- or overdosing on levothyroxine.

Conclusion

Treatment for hypothyroidism is usually lifelong, so levothyroxine is typically taken every day as prescribed by a doctor to maintain normal thyroid hormone levels. Foods that can help support healthy thyroid function include those rich in iodine, such as marine fish and seaweed. Iodized salt is also a simple and affordable source of dietary iodine. In cases where symptoms persist or complications arise, consulting the Best ENT surgeon may be recommended for further evaluation and management.
