    In-depth guides to health conditions — symptoms, causes, diagnosis, and treatment

    A

    Atherosclerosis

    Cardiovascular

    Atherosclerosis occurs when fatty deposits called plaques build up inside artery walls, narrowing the vessels and restricting blood flow. Over time, this can lead to heart attacks, strokes, or peripheral artery disease depending on which arteries are affected.

    Atrial Fibrillation

    Cardiovascular

    Atrial fibrillation is the most common type of irregular heartbeat, where the heart's upper chambers beat chaotically and out of sync with the lower chambers. This increases the risk of blood clots, stroke, and heart failure.

    Asthma

    Respiratory

    Asthma is a chronic respiratory condition in which the airways become inflamed and narrowed, making breathing difficult. Triggers like allergens, exercise, cold air, or respiratory infections can cause flare-ups (asthma attacks) with coughing, wheezing, and chest tightness.

    Multiple Sclerosis

    Neurological

    Multiple sclerosis is an autoimmune disease in which the immune system attacks the protective myelin sheath covering nerve fibers, disrupting communication between the brain and body. Symptoms vary widely depending on which nerves are affected and can range from mild numbness to severe disability.
