Will high blood pressure cause constant yawning?
Patient: my daughter is 17 years old. she weighs 124 pounds and is 5 foot 2. she has high blood pressure with no known cause. she has a slight thickening of the muscl between the two chambers of her heart. lately she cannot stop yawning constantly. this has been going on for about a week now.I was wondering if this could be related to her blood pressure or her heart. Doctor: Hello!Thank you for asking on HCM!Regarding your concern, I would explain that persistent yawning may indicate a low perfusion of the brain. This could be related to different disorders : -chronic anemia-a low heart function-a metabolic dysfucntion-sleep apnea and obstruction of the airways.  I recommend consulting with the GP for a careful physical examination and some tests : - resting ECG and cardiac ultrasound to examine her heart structure and fucntion- blood lab tests : complete blood count, PCR, sedimentation rate, blood gas analysis, kidney and liver function tests and blood electrolytes). A polysomnography may be needed to rule in/out possible sleep apnea. Hope to have been helpful!Greetings!Dr. Iliri
