For a 35 y old man with high triglycerides doctor prescribed a 100mg aspirin daily for a month, to prevent blood clotting with exercise and healthy diet but concerned that it may cause hemorrhagic stroke? is this likely.?

You have not provided sufficient information for an informed opinion. How high are the triglycerides? He may be at more risk than blood clots. Reducing triglycerides needs losing weight, reducing intake of saturated fat, regular exercise and if need be different medications.

The high triglycerides may be best managed with diet, exercise, and medications to reduce high blood fats. Depending on how elevated the levels are, there may be risk of cerebrovascular events, and the aspirin may not prevent these alone. Concern regarding aspirin eventuating in a brain hemorrhage is unwarranted, based on your brief post. Suggest a broader evaluation via HT virtual consult.
