I've been dealing with low blood pressure, and whenever I'm lying down, it drops to around 90 over 55. It's pretty unsettling because I feel lightheaded when that happens. I've tried drinking saltwater and coffee, but it doesn't seem to help much. I've read that having a low diastolic blood pressure could lead to heart failure since the coronary heart artery gets its supply during diastole. Is this true? And what steps can I take to prevent my blood pressure from falling below safe levels? Also, is having such low blood pressure dangerous?

Low blood pressure can indeed lead to symptoms like lightheadedness, especially when changing positions. To help manage your low blood pressure, you can try increasing your salt intake and staying hydrated. Additionally, wearing compression stockings can help improve blood flow. In terms of medication, you can consider taking Midodrine to help raise your blood pressure. It is important to monitor your blood pressure regularly and consult with your healthcare provider for proper management.
