Diabetes isย a health condition caused due to poor response of insulin; insulin controls blood glucose in your body. Diabetes may not be the only reason for feeling sleepy after eating. There can be other nutritional factors at play. Feeling sleepy after a meal may also be due to inadequate physical activity, poor nutrition intake and lack of rest. This condition is known as post-meal fatigue.
High blood sugar is known to cause sleepiness i.e., whether you are diabetic or not. When your blood sugar crashes, it results in low energy and you end-up feeling sluggish. This happens when high blood sugars disrupt how your body utilises sugars.
Irregular sleep cycles, stress and exposure to sunlight, inadequate intake of water and hence feeling dehydrated can cause fatigue and soreness. These lead to sleepiness during day or night, after taking food. These are quite common though. You are advised to seek medical attention only when you regularly feel drowsy or giddy soon after eating.
If you feel very tired i.e. a complete lack of energy as you wake-up in the morning or dozing-off regularly after taking a meal, these could be distinctive sins of diabetes.
Also, feeling sleepy after a meal is a result of variations in blood sugar levels; your blood sugars may hot a low or a high. These are termed as hyperglycemia (high) or hypoglycemia (low sugars). This is one of the direct outcomes of diabetes. Most people with diabetes are sleepy after eating depending on their bodyโs response (or lack of it) to insulin.
On the other hand, non-diabetic people may encounter energy-fluctuations after food. This condition arises because of quicker absorption of foods. This causes a spike in blood sugars.
Fatigue is also caused due to damage of nerves – known as diabetic neuropathy; this can cause a tingling sensation as well as pains. It may also make you go sleepless. Diabetes Fatigue Syndrome (DFS) is another reason for getting tired. This can cause fatigue โ especially among those with diabetes. Psychological, nutritional and medical triggers are also at play here. Moreover, your daily habits play an important role in your getting it.
Type 2 diabetes symptoms
People with diabetes type 2 are likely to develop signs like frequent urges of drink water / fluids โ owing to thirstiness, peeing more often, feeling hungry regularly, staying weak and tired at almost all times, slower rates of healing โ from nicks, cuts and other such injuries; blurring of eyesight, tingling sensation on hands and legs, etc. Your skin may turn dry and develops darker patches in areas like neck, armpits, etc.
Inform your caregiving team of how quickly these signs show up, and also type of diabetes you are living with. You may also experience a marked decrease in body weight; this can occur despite a healthy lifestyle and intake of balanced diet.
Weight loss is more-often experienced when cells in the body fail to needful energy; these energies are supplied through glucose. As this system fails, your body starts depending on fats โ breaking such fatty substances your system gains access to required levels of energy. This is the reason why you see body weight dropping at a faster rate!
Signs of type 2 form of diabetes are not quick in showing up; these take a lot of time to develop. In some people, it has taken several years to become palpable. There are also cases wherein a few people have had no signs of type 2 diabetes. Those who do not develop the typical signs of type 2 diabetes may have milder versions of this blood sugar condition.
There are instances people have noticed a sudden eruption of symptoms โ with the onset of type 2 diabetes mellitus. This is when such people may know they have turned diabetic. These include erectile problems, pain in chest region โ like angina, sudden drop of sense of sight โ to name a few.
People living with type 2 diabetes may experience erratic sleeping cycles. A condition termed as obstructive Sleep Apnea ย – in short, OSA is a common condition among those with diabetes.ย
Uncontrollable sleepiness after eating
Uncontrollable levels of sleepiness soon after taking food is not fully attributed to diabetes. This can be due to internal swelling or sudden changes in blood sugars. Size of meals and timing of intake can determine the extent of sleepiness experienced after eating a meal. If food has highย levels of carbohydrates or fats in it, you are more likely to see drowsiness after eating such food items.
Uncontrollable sleepiness after eating is also related to moods, climate you live in โ and a few other factors like age, presence of any ailments, if any. A colder climate can create a gloomy mood and this can make you sleepy.
Postprandial Somnolence is a condition of energy level, felt immediately after eating. This can occur when you overeat to taking foods with high calorie content in them. You are advised to alter the foods you take and also practice deep sleeping habits to overcome it.
Lastly, if you are continuously sleeping or are feeling drowsy after taking a meal, consult with a qualified medical professional or a certified diabetologist. Your caregiving team will order a blood glucose test to understand glucose levels; such tests also help rule-out other health conditions.
