###Human: Why is blood pressure normal in the morning but increases at night? ###Assistant: Hello. She is taking lots of medicines but still if BP is raised the possibilities may be, 1. Not reducing salt intake, not following a healthy lifestyle guidelines, and not exercising. 2. Medicines may not be taken appropriately, some over-the-counter medicines such as NSAIDs may raise blood pressure. 3. 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. 4. 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.
