Disorders of Sex Hormones: Definition, Types, Causes, Pathophysiology, Symptoms, and Treatment

by

Definition: Disorders of sex hormones refer to conditions that result from imbalances in the production, regulation, or action of sex hormones (estrogen, progesterone, and testosterone). These imbalances can affect sexual development, reproductive function, and secondary sexual characteristics. Types of Disorders of sex hormones 1. Hypogonadism: Reduced function of the gonads (testes or ovaries), leading to … Read more

Thyroid Diseases: Definition, Types, Causes, Pathophysiology, Symptoms, and Treatment

by

Definition: Thyroid diseases encompass a variety of disorders that affect the thyroid gland, a butterfly-shaped gland located in the neck that produces hormones regulating metabolism, growth, and development. The primary thyroid hormones are thyroxine (T4) and triiodothyronine (T3). Types of Thyroid diseases 1. Hypothyroidism: A condition where the thyroid gland produces insufficient amounts of thyroid … Read more

Diabetes: Definition, Types, Causes, Pathophysiology, Symptoms, and Treatment

by

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels (hyperglycemia) resulting from defects in insulin secretion, insulin action, or both. It can lead to serious health complications if not properly managed. Types of Diabetes 1.

Hemophilia: Causes, Types, Symptoms, Diagnosis, Treatment, and Management

by

Hemophilia is a rare genetic bleeding disorder characterized by the deficiency or dysfunction of clotting factors in the blood, primarily factor VIII (hemophilia A) or factor IX (hemophilia B). This results in prolonged or spontaneous bleeding episodes, which can lead to serious complications. This note explores the causes, types, symptoms, diagnosis, treatment, and management strategies … Read more

Hereditary and Acquired Anemia: Causes, Pathophysiology, Symptoms, Diagnosis, Treatment, and Prevention

by

Anemia is a condition characterized by a deficiency in the number or quality of red blood cells (RBCs) or hemoglobin, leading to reduced oxygen-carrying capacity of the blood. Anemia can be broadly categorized into hereditary and acquired types, based on its underlying cause. This note explores the causes, pathophysiology, symptoms, diagnosis, treatment, and prevention of … Read more

Thalassemia: Causes, Pathophysiology, Symptoms, Diagnosis, Treatment, and Prevention

by

A thalassemia is a group of inherited blood disorders characterized by the body’s inability to produce sufficient and functional hemoglobin, resulting in anemia. Hemoglobin, the protein in red blood cells responsible for carrying oxygen, has two main components: alpha and beta globin chains. Thalassemia is categorized based on which globin chain is affected: alpha thalassemia … Read more
