Hypothyroidism

Whether weight gain, fatigue, or menstrual irregularities: hypothyroidism (underactive thyroid) can, like hyperthyroidism, give rise to numerous complaints. Fortunately, this condition is well treatable — with the agent L-thyroxine, which substitutes the body's missing hormones. Our experienced doctors are by your side with this and further medical measures in the fight against hypothyroidism at all our locations.

Hypothyroidism can present in three distinct forms requiring different diagnostic approaches. These are:

• Primary hypothyroidism, in which the gland produces insufficient hormones of its own. This manifests in laboratory tests as reduced T3 and T4 levels alongside elevated TRH and TSH levels
• Secondary hypothyroidism, in which the pituitary gland is impaired. This part of the brain normally releases the stimulating hormone TSH. In this form, neither T3, T4, nor TSH can be detected in the blood
• Tertiary hypothyroidism, in which the hypothalamus is impaired — the structure that normally produces the releasing hormone TRH. As a result, TSH, T3, and T4 levels are all reduced

The most common triggers of hypothyroidism include:

• Autoimmune conditions such as Hashimoto's thyroiditis, in which the body's own antibodies destroy thyroid tissue
• Surgery on the thyroid
• Various medications
• Severe iodine deficiency

The typical symptoms of hypothyroidism include:

• Lack of drive and energy
• Weight gain
• Feeling cold
• Constipation
• Brittle hair and hair loss
• Reduced perspiration
• Slowed heart rate
• Reduced reflexes
• Specifically in women: menstrual irregularities, including absence of periods

At avi, hypothyroidism is treated successfully with medication using L-thyroxine. Taken for life, it efficiently substitutes the missing thyroid hormones in those affected. Regular blood tests, initially every six months and later once a year, ensure the optimal long-term dosage of this well-established therapy.
