What causes people with diabetes to be tired? Two common reasons for tiredness or lethargy are having too high or too low blood sugar levels. In both cases, the tiredness is the result of having an imbalance between one's level of blood glucose and the amount or effectiveness of circulating insulin.
People who have diabetes often have poor sleep habits, including difficulty falling asleep or staying asleep. Some people with diabetes get too much sleep, while others have problems getting enough sleep.
High Blood Sugar Causes Fatigue
Fatigue is one of the most common symptoms of high blood sugar. In people with diabetes, it is referred to as diabetes fatigue. Many people with the condition feel tired all the time regardless of how well they sleep, how healthily they eat, or how much they exercise on a regular basis.
Type 2 diabetes symptoms vary from person to person. There are many symptoms of type 2 diabetes. Constantly feeling tired is a common symptom, but here are additional signs of type 2 diabetes that you should monitor. As mentioned previously, your energy levels may decrease once you develop type 2 diabetes.
Although it sounds contradictory, sleep can both raise and lower glucose levels. Our bodies experience a cycle of changes every day—called a circadian rhythm—which naturally raises blood sugar levels at night and when a person sleeps. These natural blood sugar elevations are not a cause for concern.
So how much sleep do diabetics need? Sleep quality is definitely important for diabetics, and so is sleep quantity. According to the American Association of Clinical Endocrinologists (AACE), a person's chance of having diabetes, heart disease, or stroke is reduced with 6 to 9 hours of sleep each night.
Know the Signs of Low Overnight Blood Sugar
They include shakiness, sweating, confusion, erratic behavior, headache, and lightheadedness. With nighttime hypoglycemia, you may wake up with these symptoms or with a higher blood sugar reading that results from the body's response to an overnight low.
Try to go 10–12 hours each night without eating, Sheth said. For instance, if you eat breakfast at 8:30 a.m. every morning, that means capping your nighttime meals and snacks between 8:30 and 10:30 p.m. each night.
The Dawn Phenomenon
If you have diabetes, your body doesn't release more insulin to match the early-morning rise in blood sugar. It's called the dawn phenomenon, since it usually happens between 3 a.m. and 8 a.m. The dawn phenomenon happens to nearly everyone with diabetes.
Fatigue is a common symptom of diabetes that is not limited to uncontrolled diabetes. Persons may complain of fatigue along with a variety of symptoms, which may together herald comorbid psychological, medical, metabolic or endocrine, and acute or chronic complications.
Drinking plenty of water helps your kidneys flush out excess sugar. One study found that people who drink more water lower their risk for developing high blood sugar levels. And remember, water is the best. Sugary drinks elevate blood sugar by raising it even more.
A diabetic coma is a medical emergency. If you have symptoms of high or low blood sugar and you think you might pass out, call 911 or your local emergency number. If you're with someone with diabetes who has passed out, call for emergency help. Tell the emergency personnel that the unconscious person has diabetes.
The most common causes of excessive sleepiness are sleep deprivation and disorders like sleep apnea and insomnia. Depression and other mental health conditions, certain medications, and medical conditions affecting the brain and body can cause daytime drowsiness as well.
The most obvious might be a dry mouth but you may have suspected something was amiss if you had already spent the night getting up frequently to pass urine and feeling thirsty. The thirst and increased urination of diabetes are well known and occur when blood glucoses are really high.
If hypoglycaemia isn't treated promptly and your blood glucose levels drop low enough, you may become drowsy or even lose consciousness. Most people with insulin-treated diabetes notice that the symptoms of hypoglycaemia change and become less obvious the longer they live with the condition.
"It's likely that risk factors which lead to diabetes also cause napping. This could include slightly high sugar levels, meaning napping may be an early warning sign of diabetes," he said.
The symptoms of diabetes include feeling very thirsty, passing more urine than usual, and feeling tired all the time. The symptoms occur because some or all of the glucose stays in your blood and isn't used as fuel for energy. Your body tries to get rid of the excess glucose in your urine.
If you don't eat, your blood sugar levels are lower and medication may drop them even more, which can lead to hypoglycemia. Hypoglycemia can cause you to feel shaky, pass out, or even go into a coma. When you “break” your fast by eating, you may also be more likely to develop too-high blood sugar levels.
In general: Less than 100 mg/dL (5.6 mmol/L ) is normal. 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes. 126 mg/dL (7.0 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
Low blood sugar in the mornings, also known as morning hypoglycemia, can make people feel faint, light-headed, or confused. Having low blood sugar in the mornings is common in people on medication for diabetes, though it can also happen for other reasons.
Try to eat more of the following: oats, pasta, rice (particularly basmati or brown varieties), wholemeal, granary and rye breads, wholegrain cereals (e.g. Shredded Wheat, Weetabix, Porridge, Branflakes), wholegrain crackers, fruit, vegetables and salad, beans and pulses e.g. lentils, butter beans, kidney beans.
