Featured Conditions
Acne Vulgaris
Acne vulgaris is a common inflammatory skin condition caused by blocked hair follicles and oil glands, leading to pimples, blackheads, and cysts.
Acute Coronary Syndrome
Acute Coronary Syndrome is a heart attack or severe angina caused by a sudden blockage in a coronary artery, cutting off blood and oxygen to the heart muscle.
Acute Bronchitis
A self-limiting, mostly viral inflammation of the large airways causing a persistent cough lasting 1-3 weeks.
Achalasia
Achalasia is an esophageal motility disorder caused by nerve degeneration, resulting in failure of the lower esophageal sphincter to relax and progressive difficulty swallowing.
Acute Cholecystitis
Acute inflammation of the gallbladder, mostly due to gallstone obstruction of the cystic duct, causing severe right upper quadrant pain.
Acromegaly
Acromegaly is a hormonal disorder caused by a pituitary tumor producing too much growth hormone, leading to enlarged hands, feet, and facial features.
Trending Now
Schizophrenia
A chronic, severe mental disorder characterized by hallucinations, delusions, disorganized thinking, and emotional flattening, causing severe functional impairment.
Henoch-Schonlein Purpura
A childhood vasculitis presenting with a purpuric rash on the legs, joint pain, abdominal pain, and kidney involvement.
Allergic Bronchopulmonary Aspergillosis
An allergic lung reaction to Aspergillus fungus seen in asthma and cystic fibrosis patients, causing wheezing, brownish mucus plugs, and eventually permanent lung damage if not treated.
Hypertrophic Cardiomyopathy
A genetic condition causing abnormal thickening of the heart muscle, leading to breathing problems, chest pain, and a risk of sudden cardiac death.
Small Cell Lung Cancer
A very fast-growing, aggressive lung cancer strongly linked to heavy smoking, presenting centrally in the chest and often spreading early to the brain and other organs.
Mitral Regurgitation
A valvular disorder where the mitral valve fails to close completely, allowing blood to flow backward into the left atrium during ventricular contraction.
Recently Updated
Pulmonary Arterial Hypertension
A progressive disease causing severe narrowing of the lung arteries, leading to high pressure in the lungs and ultimately right-sided heart failure.
Primary Biliary Cholangitis
An autoimmune liver disease where the immune system slowly attacks the small bile ducts in the liver, leading to bile buildup, severe itching, and fatigue.
Dilated Cardiomyopathy
A condition in which the heart's main pumping chamber becomes enlarged and weakened, reducing its ability to pump blood effectively.
Anaphylaxis
A severe, sudden, and life-threatening allergic reaction involving the whole body, causing difficulty breathing, throat swelling, and a dangerous drop in blood pressure.
Esophageal Cancer
A deadly cancer of the food pipe often discovered at an advanced stage, typically causing progressive difficulty swallowing solid foods.
Alcaptonuria
A genetic disorder causing homogentisic acid buildup, resulting in dark urine when exposed to air, blue-black connective tissue pigmentation (ochronosis), and early severe arthritis.
Ascariasis
The most common human roundworm infection, contracted via contaminated soil, causing GI upset, lung inflammation, and potentially intestinal or biliary blockage in heavy infections.
Barrett Esophagus
A change in the lining of the lower esophagus from squamous to intestinal-type cells due to chronic acid reflux, carrying a risk of developing esophageal cancer.
Nephrogenic Diabetes Insipidus
A condition where the kidneys don't respond to the hormone that tells them to hold onto water, leading to excessive urination and extreme thirst.
Metabolic Syndrome
A dangerous combination of belly fat, high blood pressure, high blood sugar, and abnormal cholesterol that dramatically increases the risk of heart attacks and diabetes.
Osteoarthritis
A wear-and-tear condition where the cartilage protecting the ends of bones wears down, causing pain, stiffness, and bone-on-bone friction in joints like the knees and hips.
Psoriasis Vulgaris
A chronic autoimmune skin disease causing red, scaly plaques on extensor surfaces, driven by overactive T-cells and rapid skin cell turnover.
