Symptoms of HIT: What to Look For
Published: Jul 27, 2024
Heparin-induced thrombocytopenia (HIT) can be a silent threat with serious consequences. Learn about the symptoms to watch for in this condition.
Thrombocytopenia
The hallmark of HIT is a significant drop in platelet count, often seen 5 to 10 days after starting heparin. This drop can lead to symptoms like unusual bruising or bleeding. Monitoring platelet levels is vital for early detection and intervention.
Thrombosis
HIT can lead to dangerous blood clots in veins or arteries, known as thrombosis. Symptoms may include swelling, pain in the limbs, or sudden shortness of breath if pulmonary embolism occurs. These signs require immediate medical attention.
Skin Reactions
Some people experience skin reactions like redness or necrosis at heparin injection sites. Although less common, these symptoms can be an early warning sign of HIT. Recognizing these symptoms can prevent further complications.
