Why is blood pressure normal in the morning but increases at night?

Question

Hello doctor,

My mother's blood pressure is 130/80 mmHg in the morning, but by 10 pm before she eats her medicine in the night, her bp becomes 160/80. She is taking calcium channel blockers, which cause swelling in her legs resulting in difficulty in walking. She is currently under Moxilong 0.3 mg tablet twice, Tazloc 40 twice, Ecosprin AV 75 in the night, Minipress XL 5 mg twice, Prolomet XL 50 twice and Dytor 5 and Benidipine 8.

Hello,

Welcome to icliniq.com.

She is taking lots of medicines but still if BP (blood pressure) is raised the possibilities may be, not reducing salt intake, not following a healthy lifestyle guidelines, and not exercising, medicines may not be taken appropriately, some over-the-counter medicines such as NSAIDs may raise blood pressure. She is overweight, and as such if BP apparatus cuff bladder is less than 2/3rd of arm circumference, then BP may falsely appear high. Some other disease such as hypothyroidism may be present, leading to secondary hypertension. Serum TSH (thyroid-stimulating hormone) test is advised for that. Please consider these issues while measuring BP.
