Question 2

What causes swelling in the feet?

Accepted Answer

Foot swelling, or pedal edema, refers to the accumulation of excess fluid in the tissues of the feet and ankles. It can result from a wide range of underlying causes—some benign and transient, others indicative of serious systemic disease. Common non-urgent contributors include prolonged standing or sitting, venous insufficiency (where incompetent valves in leg veins impair blood return to the heart), mild trauma, or localized infection. Certain medications—such as calcium channel blockers (e.g.

Question 3

What are the implications of low creatinine levels?

Accepted Answer

Low serum creatinine levels are generally not considered clinically significant on their own and rarely indicate a serious underlying condition. Creatinine is a waste product generated from the normal breakdown of creatine phosphate in muscle tissue, and its concentration in the blood reflects both muscle mass and kidney filtration function. Therefore, low creatinine most commonly reflects reduced skeletal muscle mass—such as in older adults, individuals with malnutrition, cachexia, or chronic i

Question 4

What should I do when my legs are slightly swollen?

Accepted Answer

When you notice mild swelling (edema) in your legs, it’s important to first assess for potential causes and determine whether immediate medical evaluation is needed. Leg edema can result from a variety of conditions—ranging from benign and reversible factors (e.g., prolonged standing or sitting, high sodium intake, or mild venous insufficiency) to more serious underlying issues such as heart failure, chronic kidney disease, liver cirrhosis, deep vein thrombosis (DVT), or medication side effects

Question 5

What are the treatment options for acute nephritis?

Accepted Answer

Acute glomerulonephritis is typically a self-limiting immune-mediated condition, most commonly triggered by a preceding streptococcal infection—such as pharyngitis or impetigo—leading to post-infectious glomerulonephritis. Management focuses on supportive care and close monitoring rather than specific immunosuppressive therapy, as the disease usually resolves spontaneously over weeks to months.

Initial treatment emphasizes control of hypertension and fluid overload, often requiring sodium and f

Question 6

What are the causes of facial swelling in elderly people?

Accepted Answer

Facial swelling in older adults can arise from a variety of underlying causes, ranging from benign and transient to serious and potentially life-threatening. Common contributors include fluid retention (edema) due to heart failure—particularly right-sided or global heart failure—where reduced cardiac output leads to venous congestion and capillary hydrostatic pressure elevation, promoting interstitial fluid accumulation. Chronic kidney disease may also cause facial edema, especially in the perio

Question 7

What causes facial swelling and what should I do about it?

Accepted Answer

Facial swelling, or facial edema, refers to the accumulation of excess fluid in the soft tissues of the face. It can involve one or both sides and may affect areas such as the eyelids, cheeks, lips, or jaw. The underlying cause determines both the clinical presentation and urgency of management.

Common benign causes include allergic reactions (e.g., to foods, medications, insect stings, or environmental allergens), acute sinusitis, dental infections (such as abscesses or periodontal cellulitis)
