What is the treatment for mildly raised blood pressure?

You appear to have mild hypertension. However this must be confirmed by several readings say once in 2 weeks. You must first try simple methods of BP control after a full check up which should include full biochemical tests, ECG, X-ray chest. These measures are

• Diet should be low in salt & fat. Your weight is O.K.
• Regular exercise - walk an hour daily
• No alcohol or smoking

If your BP is still above 140/90 mmHg you can start drugs. I suggest you get the advice of your doctor for this.
