Hashimoto’s disease, also known as Hashimoto’s thyroiditis, is an autoimmune disorder that can cause hypothyroidism or underactive thyroid. With this condition, the immune system attacks the thyroid gland, leading to inflammation and interfering with its ability to produce thyroid hormones. The thyroid, a small gland at the base of the neck, plays a crucial role in regulating numerous metabolic processes throughout the body via the release of hormones.
Causes and Risk Factors
The exact cause of Hashimoto’s is not fully understood, but it is believed to involve a combination of genetic susceptibility and environmental factors. Certain genes increase the risk, and having a family member with Hashimoto’s or another autoimmune disease may also increase the risk. Environmental factors, including selenium deficiency, high iodine intake, and radiation exposure, are believed to contribute to the development of the disease.
Symptoms
The symptoms of Hashimoto’s disease can be subtle at first and then become more noticeable. They typically develop slowly over the years and may include:
- Fatigue and sluggishness
- Increased sensitivity to cold
- Constipation
- Pale, dry skin
- A puffy face
- Hoarse voice
- High cholesterol
- Unexplained weight gain
- Muscle aches, tenderness, and stiffness
- Joint pain and stiffness
- Muscle weakness
- Heavy or irregular menstrual periods
- Thinning hair
- Slowed heart rate
- Depression
Diagnosis
Diagnosing Hashimoto’s disease involves a review of symptoms, a physical examination, and specific diagnostic tests. Blood tests can measure levels of thyroid-stimulating hormone (TSH) and thyroxine. In Hashimoto’s disease, TSH levels are usually elevated because the pituitary gland is trying to stimulate the thyroid gland to produce more thyroid hormone. The blood test can also detect antibodies against thyroid peroxidase (TPO antibodies), which are present in most Hashimoto’s cases.
Treatment
While there is no cure for Hashimoto’s thyroiditis, treatment typically involves hormone replacement therapy to normalize hormone levels and alleviate symptoms. Levothyroxine, a synthetic form of thyroxine (T4), is commonly prescribed. The dosage is carefully monitored and adjusted based on regular blood tests to ensure the TSH levels are within the target range.
Living with Hashimoto’s Disease
Managing Hashimoto’s disease requires ongoing monitoring and treatment adjustments. Patients can live normal, healthy lives with proper treatment. Lifestyle changes, such as adopting a balanced diet, regular exercise, and stress management techniques, can help manage symptoms and improve overall well-being.
