Doctor-Reviewed Health Guides: Conditions, Procedures & Health News

An enlarged liver, or hepatomegaly, is a liver larger than normal for a person's age, sex and body size. It may cause no symptoms, or belly pain, fatigue, nausea and jaundice. Causes include hepatitis, fatty liver disease, cancers and congestive heart failure. Diagnosis uses an exam, blood tests and imaging, and treatment targets the underlying condition.

Polydipsia is extreme, persistent thirst that cannot be satisfied by drinking normal or even large amounts of fluid. Unlike ordinary thirst after exercise or salty food, it is an abnormal urge to drink that can last days or months. It is often a key sign of underlying conditions, especially diabetes mellitus or diabetes insipidus, and requires clinical evaluation.

A pimple on the penis is often a blocked hair follicle or oil gland, similar to acne elsewhere on the body. It may also be a normal, harmless feature like pearly penile papules or Fordyce spots. If a bump comes with pain, a rash, or follows unprotected sexual contact, see a healthcare provider for diagnosis and treatment.

Pitting edema is swelling that leaves a pit or dent after you press on the swollen area, caused by excess fluid trapped in tissues, usually in the legs or feet. It often points to serious problems such as heart failure or kidney disease and is graded from 1 to 4. Treatment manages the underlying condition, plus compression or elevation.

Left-side chest pain is pain that can come from the heart, lungs, stomach, muscles or anxiety, with acid reflux the most common cause. Many causes are not dangerous, but a heart attack cannot be ruled out at home. Call emergency services if pain is new, sudden or lasts over 5 minutes, especially with shortness of breath, sweating or spreading pain.
