Hello!
Welcome and thank you for asking on HCM!
I understand your concern and would explain that your situation could be related to different causes.
I would like to know your actual blood pressure and heart rate values.
If your blood pressure or heart rate is low, this could be related to propranolol intake.
But, I don't think so, because you have been using propranolol for 5 years without any of these symptoms.
A metabolic disorder could be related to this symptomatology.Dehydration could lead to low blood pressure and fainting.
I would recommend consulting with your attending physician for a careful physical exam and some tests:
- a resting ECG
- blood lab tests (complete blood count, thyroid hormone levels, fasting glucose, blood electrolytes, kidney and liver function tests) to exclude possible disorders like chronic anemia, thyroid imbalance, electrolyte imbalances, etc.
- a Head up Tilt test to exclude possible orthostatic intolerance which could explain your symptoms.
Meanwhile, I recommend you to closely monitor your heart rate and blood pressure values (in sitting and standing up position) and refer them to your doctor.
Hope you will find this answer helpful!
Kind regards,
Dr. Iliri

Hello again!
Thank you for the additional information.
I would exclude propranolol as the cause of your symptoms. A metabolic disorder or a hormonal imbalance could be the cause of your persistent dehydration.
Besides, dehydration can lead to fainting and dizziness.
I recommend performing thyroid hormone levels, fasting glucose levels, blood electrolytes, blood osmolarity, urine analysis including urine osmolarity and plasma antidiuretic hormone (ADH) levels, to exclude possible disorders related to this hormone. This hormone could be responsible for poor urine concentration and the thirst feeling.
If all these tests result normal, you should consider anxiety too as a possible cause of your symptoms.
Meanwhile, I recommend taking a lot of water to avoid dehydration.
Hope to have been helpful!
Best wishes,
