It sounds like you're concerned about your blood pressure readings, fasting sugar level, and severe headaches, which is understandable.

• Blood Pressure of 110-170: This range shows a significant variation, with the higher value (170) indicating elevated blood pressure (hypertension). High blood pressure can increase the risk of heart disease and stroke. Managing it often requires medication, lifestyle changes, and regular monitoring.

• Fasting Sugar of 100 mg/dL: This value is at the upper limit of normal fasting blood glucose. It may suggest prediabetes if consistently elevated, but alone it is not diagnostic of diabetes.

• Severe Headaches on the Left Side: Such headaches could be related to high blood pressure or other causes like migraines or neurological issues. Given the severity and location, it is important to have this evaluated promptly.

You mentioned a medication called Cosart-H, which combines Losartan and Hydrochlorothiazide, commonly used to treat high blood pressure by relaxing blood vessels and reducing fluid retention.

Recommendations:

• Please consult a cardiologist or a neurologist promptly to evaluate your blood pressure control and investigate the cause of your severe headaches.
• Regular monitoring of blood pressure and blood sugar is important.
• Do not adjust or stop any prescribed medication without your doctor's advice.
• If headaches worsen, or you experience symptoms like vision changes, weakness, or confusion, seek emergency care immediately.
