<s>[INST] Last week I suddenly developed high blood pressure ranging from the 190 s over 90 s. I t hought it was too much salt in my recent diet and starting drinking water and watching my salt intake. My doctor doubled my enalipril beselate to 20 mg per day, but a week later the BP is just as bad and now I am drinking water because I am always thirsty. [/INST] HelloThanks for posting at HCM. Your BP is definitely high hence your doctor has doubled your enalapril dose. You have to wait for at least two weeks for the blood pressure to be under control. Drinking lots of water also increases the blood volume and contributes to high BP. Frequent thirst is a symptom of diabetes. Hence please check your fasting and post lunch blood sugars. If BP remains persistently higher despite increased dose of enalapril, a renal Doppler study and a 2 d echo should be done. Also an additional BP medication should be added in that case. wishing you good healthRegards </s>
