Ezetimibe lowers LDL cholesterol by blocking intestinal absorption through NPC1L1, typically reducing LDL by 15–25% alone and more when combined with a statin. Clinical trials show it lowers heart attack and stroke risk when added to statin therapy. Doctors often prescribe ezetimibe when statins alone aren't enough or aren't tolerated, and it's generally well tolerated with few side effects. Key considerations include your specific lipid numbers, 10-year cardiovascular risk, lifestyle changes, medication options (statin plus ezetimibe or alternatives), and follow-up lipid testing at 4–12 weeks. Full details—including red flags requiring urgent care—are below. Since cholesterol management depends heavily on your individual symptoms, risk factors, and overall health picture, guessing your next step can waste time or delay important care.

High hematocrit means your red blood cell percentage is higher than normal. Common symptoms include headaches, dizziness, blurred vision, facial flushing, fatigue, shortness of breath, itching, and tingling. In severe cases, high hematocrit increases the risk of dangerous blood clots and requires urgent medical care. Dehydration is one of the most common causes, since fluid loss concentrates red blood cells in the bloodstream. However, other causes include smoking, living at high altitude, sleep apnea, heart or lung disease, certain medications, and polycythemia vera (a bone marrow disorder). Doctors typically evaluate high hematocrit through blood tests, medical history, and sometimes imaging or bone marrow studies, with treatment tailored to the underlying cause.
