High Cholesterol: Silent Signs, Visible Clues & What "Blood in Urine" Really Means

High cholesterol (hyperlipidemia) is typically asymptomatic. Most people discover it through routine screening. However, certain physical signs can indicate severe or genetic forms.

Visible Signs of Significant Hyperlipidemia

Sign	Description	Associated Condition
Xanthelasma	Soft, yellowish plaques on medial eyelids	Often familial hypercholesterolemia; can occur with normal lipids
Corneal Arcus (Arcus Senilis)	White/gray ring at corneal periphery	Age-related if >50; if <45, suggests familial hyperlipidemia
Tendon Xanthomas	Firm nodules on Achilles tendons, hand extensors	Pathognomonic for Familial Hypercholesterolemia (FH)
Tuberous Xanthomas	Firm, painless nodules over joints (elbows, knees)	Severe hypertriglyceridemia, dysbetalipoproteinemia
Eruptive Xanthomas	Crops of small, itchy, yellow papules (buttocks, extensor surfaces)	Severe hypertriglyceridemia (>1000 mg/dL); pancreatitis risk

Vascular Complications (Late Signs)

• Peripheral Artery Disease (PAD): Claudication, diminished pulses, cool extremities, poor wound healing.
• Carotid Artery Disease: Bruits, TIA, stroke.
• Coronary Artery Disease: Angina, MI — often first presentation.

Clarification: "Blood in Urine" (Hematuria) ≠ High Cholesterol

The original text conflated two unrelated questions. Hematuria (blood in urine) has its own differential:

• UTI / Pyelonephritis
• Nephrolithiasis (stones)
• Glomerulonephritis (autoimmune, post-infectious)
• Malignancy (bladder, kidney, prostate)
• BPH (benign prostatic hyperplasia)
• Anticoagulants / Antiplatelets
• Exercise-induced (benign, transient)

Action: Any hematuria → urinalysis, culture, imaging (CT urogram), cystoscopy if persistent/risk factors.

Cholesterol Screening & Management

• Screen: Lipid panel (fasting preferred for triglycerides). Age 20+ every 4–6y; earlier/frequent if risk factors.
• Targets (ACC/AHA): LDL-C <70 mg/dL (ASCVD), <100 (high risk), <130 (primary prevention). Non-HDL-C <100/130 respectively.
• Therapy: Statins (intensity by risk), Ezetimibe, PCSK9 inhibitors, Bempedoic acid, Icosapent ethyl (high TG + CVD).
• Lifestyle: Mediterranean diet, soluble fiber (5–10g), plant sterols, exercise, weight loss, limit sat fat/trans fat/alcohol.

Bottom line: High cholesterol is silent. Visible signs (xanthelasma, arcus, tendon xanthomas) signal genetic/severe disease. Hematuria is a separate urologic/nephrologic issue. Know your numbers. Treat risk, not just lipids.
