Glandular disorders refer to conditions that affect the glands in the body, which are responsible for producing hormones and other important substances. These disorders can occur in various glands, such as the thyroid, pancreas, and adrenal glands. Common examples include hypothyroidism, where the thyroid does not produce enough hormones, and diabetes, which involves issues with insulin production in the pancreas. Symptoms of glandular disorders can vary widely depending on the affected gland. They may include fatigue, weight changes, mood swings, and changes in metabolism. Diagnosis often involves blood tests to measure hormone levels, and treatment may include medication, lifestyle changes, or surgery, depending on the specific disorder.
