Since your mother’s blood pressure has remained elevated at around 170/94 mmHg despite recent medication changes, it is important to continue regular blood pressure monitoring and to follow up immediately with her treating physician or cardiologist for a comprehensive clinical evaluation. Please ensure you share her daily blood pressure readings and her recent normal electrolyte results (sodium 138 mmol/L, potassium 4.2 mmol/L) during the consultation so the doctor can review her treatment plan safely. Do not change, add, or stop any of her blood pressure medicines without direct medical advice. Additionally, please seek urgent medical care immediately if she develops any red-flag symptoms such as chest pain, breathlessness, severe dizziness, confusion, sudden weakness, or vision changes.
