Thyroid Disorders

Endocrine System Role

The endocrine system comprises glands like the thyroid, pituitary, adrenals, and pancreas that secrete hormones regulating metabolism, growth, reproduction, and mood. Imbalances arise from over- or under-production, gland damage, or poor hormone response, affecting multiple organs. Diabetes tops prevalence, impacting millions worldwide.

Common Disorders

Thyroid issues dominate: hypothyroidism causes fatigue, weight gain, cold intolerance; hyperthyroidism leads to weight loss, tremors, rapid heartbeat. Adrenal disorders include Cushing's syndrome (excess cortisol, moon face, hypertension) and Addison's disease (fatigue, low blood pressure). Pituitary problems like hypopituitarism halt hormone release, disrupting periods or growth.

Symptoms Overview

Fatigue, unexplained weight fluctuations, mood swings, infertility, skin changes, bone fragility signal issues. Diabetes presents with thirst, frequent urination, blurred vision; PCOS features irregular cycles, acne, excess hair. Heart rate changes, high blood sugar, or calcium levels often prompt evaluation.

Diagnosis and Management

Blood tests measure hormone levels; imaging scans glands. Treatments involve medications (levothyroxine for hypothyroidism), surgery for tumors, lifestyle changes, or hormone replacement. Early intervention prevents complications like osteoporosis or cardiovascular disease.
