A nap or a short nap after eating, especially lunch, may turn into a chronic habit for many, but a certain group must pay attention to that drowsiness, lack of concentration and general weakness after eating rings an alarm bell, who are these? What should they do?

Many feel sleepy after eating, and take a short nap; This may be natural, but some people should take care, especially those with diabetes, for example, according to Deutsche Welle quoted by the website "aponet.de", which follows the "Federal Association of German Pharmacists Associations" (ABDA) .

After eating, the blood sugar level rises very quickly, and this carries risks for people with type 2 diabetes, according to Johanna Sander, a diabetes expert.

The sufferers rarely notice this, and even doctors cannot discover this when they perform the glycosylated hemoglobin (HbA1c) test, that is, a blood test to detect the level of sugar in the blood for several months ago, which is known to the public as a "cumulative sugar" test.

Hence, the German expert advises that a diabetic who feels sleepy and tired after eating should check the blood sugar level two hours after a meal, and then discuss the results with the doctor, to see if there is a need to adjust the insulin doses or the medicine provided to the patient, or even provide insulin doses after the food.

And Johanna Sander warns that leaving it untreated may carry with it health risks, such as a deterioration in the condition of those suffering from cardiovascular diseases, damage to blood vessels in the eyes, and damage to the perception and memory of elderly diabetics.
