What Causes Rapid Heartbeat At Night While Sleeping?
Possible Nocturnal Hypoglycemia?Loss of insulin secretion regulation.
Detailed Answer:
Hi Mam,
I understand your query and concern.
As per your history suggested you seem to have nocturnal sudden dips in blood glucose which is contributing to symptoms of autonomic/sympathetic overdrive leading to a bout of elevated heart rates manifested as palpitations.
This is keep you awake at mid night disturbing your sleep.
These nocturnal dips in blood glucose could be related to variations in the insulin release in response to high calorie intake prior to falling asleep.This is leading to large release of insulin causing excess glucose to be removed from circulation contributing to nocturnal or early morning hypoglycemia.
The same can happen if you consume low calorie foods prior to sleep.
The sensation of bloating along with high gastric residue seem to be related to Gastroparesis,a condition of autonomic nervous system dysfunction leading to such symptoms
All these symptoms are possibly related to the loss of regulation of insulin secretion and a latent diabetic state.
Hence I advice you to have a complete testing of fasting as well as postprandial glucose levels along with HB1ac levels which predict the average glucose control over the preceding 3 months.
They are also excellent tools in diagnosing latent diabetes,particularly individuals with family history of diabetes as in your case.
I also recommend you to have a baseline EKG along with Continuous ambulatory 24 hr ecg recording to rule the possibility of cardiac conduction disturbances,which are quite prevalent in diabetic and pre diabetics.
Many of your current symptoms can be controlled with nocturnal insulin supplementation in adequate doses in proportion to the blood glucose levels.
Consultation with an Endocrinologist is pretty mandate in your case.
Post your further queries,if any.
Thank you.
