And although little has been mentioned about caregivers and parents of diabetes patients, they are more likely to acquire poor sleeping habits and have a higher tendency to suffer from sleeping problems and consequently develop Type 2 diabetes themselves. So if you have diabetes or are currently caring for someone who has diabetes, this article will educate you more about how sleeping disorders can affect your health and how you can get better sleep. This article will cover the following topics: Relationship Between Sleep and Diabetes Your health and sleep go hand in hand. When you do not sleep enough, your body does not get the needed time to repair. As a result, you tend to be unfocused and irritable, and you suddenly have the urge to eat. If this scenario sounds too familiar to you, maybe you should rethink about the relationship between sleep and your diabetes. The Missing Link — Hormones Sleep plays a crucial role in restoring our body cells. Under healthy conditions, after eating, the pancreas secretes insulin to signal fat cells and muscles to absorb the glucose from food to be used for energy creation and prevents the body from using fat as energy source. This chain of reaction causes the blood glucose levels to resume normal. And to prevent the individual from feeling hungry, the body produces the hormone leptin to depresses the appetite. However, when it comes to diabetes individuals, the muscle and fat cells fails to respond to insulin. This causes a high glucose level in the bloodst Continue reading >>

Why do I feel tired after eating sugar?

Popping these stuffs would provide you with an instant burst of energy, but on the other hand, this instant burst would die soon. Consuming sugar increases the metabolism of the body , and hence you feel sleepy and tired. Although medical practitioners and researchers have always condemned the use of excessive sugar, there are very few people who understand the reason behind it. People usually think that consuming sugar would provide them with instant energy. This however is not true. You might feel energetic for sometime after having sugar because of the increased metabolism, but as soon as the sugar is burnt you start feeling tired and sleepy. Researchers have a lot to say on this topic. One of the main reasons as to why you feel tired is explained below. When you consume sugar or product containing a high amount of sugar, then it causes an increase in the blood sugar levels. The increase in the blood sugar level results the release of insulin from the pancreas, which would result in sudden decrease of the blood sugar levels. This sudden diminishing of the levels makes you feel sleepy and tired. This can also result in cravings in your body as it tries to recover from this sudden change. The sluggishness caused as a result of sugar consumption can also be attributed to sugar sensitivity. This is caused when you have an increased blood sugar level because of low serotonin and low beta-endorphin. Both beta-endorphin and serotonin are chemicals that are found in the brain. When the level of serotonin is low, then you will experience fatigue, and at times would be unable to focus on issues. If the level of beta-endorphin falls, then it can result i Continue reading >>

How long after eating can you have reactive hypoglycemia?

I think I have reactive hypoglycemia. How can I address my symptoms? Answers from M. Regina Castro, M.D. Reactive hypoglycemia (postprandial hypoglycemia) refers to low blood sugar that occurs after a meal — usually within four hours after eating. This is different from low blood sugar (hypoglycemia) that occurs while fasting. Signs and symptoms of reactive hypoglycemia may include hunger, weakness, shakiness, sleepiness, sweating, lightheadedness and anxiety. It's possible to have symptoms that are similar to reactive hypoglycemia without actually having low blood sugar. True reactive hypoglycemia symptoms that are caused by low blood sugar occurring after eating are uncommon. For the majority of people with postprandial symptoms, the actual cause of the symptoms is not clear but may relate to what food was eaten or variations in the timing of the food moving through the stomach and intestinal tract. Generally, a medical evaluation is done to determine whether symptoms are caused by low blood sugar — and whether symptoms resolve once blood sugar returns to normal. Further evaluation of reactive hypoglycemia depends on the severity of symptoms. For the majority of people, reactive hypoglycemia usually doesn't require medical treatment. It may help, however, to pay attention to the timing and composition of your meals: Eat a well-balanced diet, including lean and nonmeat sources of protein, and high-fiber foods, including whole grains, fruits and vegetables. Avoid sugary foods, especially on an empty stomach. Be sure to eat food if you're consuming alcohol, and avoid using sugary soft drinks as mixers. Eat several small meals and snacks throughout the day, no more than three hours apart during the waking hours. Most people will try to find out what dietary changes ar Continue reading >>

How can I prevent diabetes?

One of the best ways to prevent diabetes is to spot blood sugar (glucose) problems before the full-blown disease develops. But most people don’t realize that diabetes — and its precursor, prediabetes — can cause no symptoms at all or a wide range of symptoms that often are misinterpreted. Common mistake: Because diabetes is strongly linked to excess body weight, many people who are a normal weight assume that they won’t develop the disease. But that’s not always true. About 15% of people who are diagnosed with diabetes are not overweight. And paradoxically, even weight loss can be a symptom of this complex disorder in people (normal weight or overweight) who have uncontrolled high glucose levels. Shocking new finding: The Centers for Disease Control and Prevention now estimates that 40% of Americans ages 40 to 74 have prediabetes, and nearly two out of three Americans over age 65 have prediabetes or diabetes — most likely due to the increasing numbers of people who are overweight and inactive, both of which boost diabetes risk. However, most primary care doctors aren’t diagnosing and treating prediabetes early enough in their patients — often because they fail to order the necessary screening tests. And because the symptoms of prediabetes can be subtle, especially in its early stages, most people are not reporting potential red flags to their doctors. Fortunately, prediabetes can virtually always be prevented from progressing to diabetes if the condition is identified and treated in its early stages (by following a healthful diet, exercising regularly and taking nutritional supplements and medications, if necessary). Being overweight (defined as having a body mass index, or BMI, of 25 or higher) is perhaps the best-known risk factor for diabetes.* The mo Continue reading >>

Does sleep affect diabetes?

SLEEP PROBLEMS AND SNORING MAY PREDICT DIABETES Studies have shown that individuals who consistently have a bad night's sleep are more likely to develop conditions linked to diabetes and heart disease. Loud snoring sleepers (many of whom may have sleep apnea), compared to quiet sleepers, double (2x) their risks of developing certain types of metabolic syndrome (s); including diabetes, obesity, and high blood pressure. This likelihood also increased dramatically to 80% in those who found it difficult to fall asleep and to 70% for those who woke up feeling not as refreshed. Blood Sugar and Sleep Problems Sleep can affect your blood sugar levels, and your blood glucose control can also affect your sleep. It’s a vicious cycle. As the amount of sleep decreases, blood sugar increases, escalating the issue. Lack of sleep has been shown to increase blood sugar levels and the risk of diabetic issues. Higher blood sugar means less long-lasting fat metabolism in the night and even less sleep. Researchers at Boston University School of Medicine found that people who slept less than 6 hours a night had more blood sugar complications compared to those who received 8 hours of sleep. HIGH BLOOD SUGAR - HYPERGLYCEMIA Sleepless and restless nights hurt more than your mood and energy; it is a form of chronic stress on the body. When there is added stress on your body this results in having higher blood sugar levels. When researchers restricted people with type-1 diabetes to just 4 hours of sleep, their sensitivity to insulin was reduced by 20% compared to that after a full nig Continue reading >>
