In people without diabetes, blood glucose (sugar) is regulated by the body to promote healthy blood sugar levels. <\/p>\n\n\n\n
High and low blood sugar levels can be dangerous and cause life-threatening problems. Therefore, the main goal when managing diabetes is to keep blood sugar levels in a healthy range to avoid health complications. <\/p>\n\n\n\n
People without diabetes can even experience high or low blood sugar<\/a> at times. <\/p>\n\n\n\n Being aware of the symptoms of blood sugar imbalances, such as low blood sugar, is essential to help prevent the development of Hypoglycemia. <\/p>\n\n\n\n The body\u2019s primary source of energy is sugar in the form of blood glucose. There is always some sugar present in our blood for us to survive. <\/p>\n\n\n\n For our bodies to effectively use sugar to fuel our cells, the hormone insulin <\/a>is required. Insulin helps sugar get from the blood into our cells; this action lowers our blood sugar. <\/p>\n\n\n\n Hypoglycemia is the term for low blood sugar<\/a>, or when blood glucose falls below 70 milligrams per deciliter (mg\/dL). When blood sugar is low, it causes harmful and disruptive symptoms. <\/p>\n\n\n\n Prolonged periods of severe hypoglycemia can cause insulin shock. Insulin shock can be life-threatening and lead to coma and death if it\u2019s not treated quickly. <\/p>\n\n\n\n Hypoglycemia usually occurs in people with diabetes mellitus<\/a> or diabetes. Diabetes occurs when the pancreas doesn\u2019t make enough insulin, or it doesn\u2019t respond to insulin-like it should. <\/p>\n\n\n\n Without enough insulin, blood sugar levels are too high. People with diabetes often take medication, such as insulin, to help lower blood sugar to a healthy level.<\/p>\n\n\n\n Hypoglycemia usually occurs when there is too much insulin present in the body, which explains the term insulin shock<\/a>. <\/p>\n\n\n\n <\/p>\n\n\n\n There are many warning signs of hypoglycemia. <\/p>\n\n\n\n The most common symptoms of hypoglycemia include: <\/p>\n\n\n\n Some people experience nocturnal hypoglycemia, which means it occurs overnight while sleeping. Signs of nocturnal hypoglycemia include: <\/p>\n\n\n\n If hypoglycemia isn\u2019t treated, severe hypoglycemia<\/a> can occur. Signs and symptoms of severe hypoglycemia include: <\/p>\n\n\n\n There are many causes of hypoglycemia. Many of them are related to diabetes, but some people without diabetes can also develop hypoglycemia. <\/p>\n\n\n\n Injecting insulin lowers blood sugar more quickly than any other diabetes medication. The risk of low blood sugar is highest with short- and rapid-acting insulins. <\/p>\n\n\n\n Regular insulin is short-acting, and Humalog and Novolog are examples of rapid-acting insulins. Fast-acting insulin is usually taken around meals because eating raises blood sugar. <\/p>\n\n\n\n Long-acting or basal insulin works the slowest out of all of the different insulins. It is usually injected once or twice a day. Long-acting insulin mimics the body\u2019s natural ability to release a minimal amount of insulin continuously, like a faucet dripping. <\/p>\n\n\n\n Examples of long-acting insulin<\/a> include Lantus and Levemir<\/a>. Newer concentrated and ultra-long-acting insulin such as Toujeo, Tresiba, and Basaglar are also considered basal insulins. <\/p>\n\n\n\n Intermediate-acting insulin works more slowly than fast-acting but is faster than basal insulin. Examples of intermediate insulins are Novolin N and Humulin N, or NPH insulin. <\/p>\n\n\n\n Insulin doses can overlap, which increases the risk of hypoglycemia. For example, taking a morning dose of NPH insulin as well as a dose of rapid-acting insulin before lunch can cause a \u201cstacking up\u201d of insulin levels in the body. <\/p>\n\n\n\n Other diabetes medications that aren\u2019t insulin can also cause hypoglycemia. These medications include: <\/p>\n\n\n\n People who have had diabetes for a long time may not be as aware of the symptoms of hypoglycemia. This can occur as a result of autonomic neuropathy<\/a>, which is a complication of long-term high blood sugar. <\/p>\n\n\n\n Not enough food, especially carbohydrates. Foods that contain carbohydrates, such as bread, milk, fruit, and starchy vegetables, turn into sugar when digested. If someone isn\u2019t eating very many carbohydrates, especially if they\u2019re also taking insulin, hypoglycemia can occur. <\/p>\n\n\n\n Physical activity stimulates the body to take up more glucose for energy, which can cause low blood sugar<\/a> if food or drink containing carbohydrates aren\u2019t taken in regular amounts while exercising for long periods of time. <\/p>\n\n\n\n This is one of the reasons marathon runners usually take energy gels or drinks containing sugar throughout their run. <\/p>\n\n\n\n The liver stores sugar in the form of glycogen. Glycogen helps provide our bodies with sugar when we are fasting and during exercise, thus reducing hypoglycemia risk. <\/p>\n\n\n\n During prolonged periods of exercise or fasting, glycogen stores can become used up. Severe weight loss<\/a> can also use up glycogen stores due to being in a fasting state. Without enough glycogen, hypoglycemia can occur. <\/p>\n\n\n\n Some people with and without diabetes produce too much insulin in response to eating, especially simple sugars like candy and juice. Reactive hypoglycemia<\/a> usually occurs within a few hours after eating and can happen very quickly in some cases. <\/p>\n\n\n\n Gastroparesis<\/a> is the slowing of stomach emptying, which can occur as a complication of diabetes. When food isn\u2019t emptied from the stomach very quickly, it isn\u2019t available to be digested and converted into sugar in the bloodstream. <\/p>\n\n\n\n Hypoglycemia risk increases in people with gastroparesis who take insulin. Some healthcare providers recommend taking mealtime insulin after a meal (instead of before) in the case of severe gastroparesis to reduce hypoglycemia risk. <\/p>\n\n\n\n Alcohol<\/a> can cause an increase in insulin secretion as well as interferes with the liver\u2019s ability to create sugar (gluconeogenesis), which can both cause hypoglycemia. <\/p>\n\n\n\n Other causes not related to diabetes: Pancreatic tumors, adrenal or pituitary problems, kidney problems<\/a>, liver problems, and certain non-diabetic medications can all cause hypoglycemia. <\/p>\n\n\n\n Hypoglycemia is diagnosed using a blood test. If you don\u2019t have diabetes and aren\u2019t checking your blood sugar regularly, it can be hard to know how low your blood sugar is. <\/p>\n\n\n\n On the other hand, people checking their blood sugar regularly can easily identify hypoglycemia by performing a fingerstick blood sugar test<\/a>. <\/p>\n\n\n\n Hypoglycemia is diagnosed when blood glucose is below 70 mg\/dL. Some people may feel symptoms of low blood sugar<\/a> while their blood sugar is actively dropping. <\/p>\n\n\n\n In this case, it\u2019s important to recheck blood sugar, even if the reading is normal because it could be low after the recheck. <\/p>\n\n\n\n If someone is experiencing low blood sugar outside of eating or fasting, blood sugar tests may be ordered for several days in a row.<\/p>\n\n\n\n For reactive hypoglycemia, a mixed meal tolerance test (MMTT) may be ordered. An MMTT involves drinking a drink containing protein, fat, and sugar, and having your blood sugar tested several times during the next few hours. <\/p>\n\n\n\n The results of the test can help determine how much insulin is being secreted in response to eating. <\/p>\n\n\n\n Eating a hypoglycemia diet<\/a>, including protein, fat, and carbohydrates every few hours can help keep blood sugar levels stable. For people with reactive hypoglycemia, avoiding simple sugars may help prevent hypoglycemia. Simple sugars, such as soda and sweets, stimulate the pancreas<\/a> to release insulin more quickly than foods like fruit and bread. A rapid increase in insulin levels can cause low blood sugar<\/a>. <\/p>\n\n\n\n Insulin is a potentially dangerous medication because it\u2019s so effective at reducing blood sugar. Insulin should only be used under the guidance of a healthcare provider, and only as prescribed.<\/p>\n\n\n\n If your blood sugar levels are high, discuss it with your healthcare provider; never increase insulin doses on your own, as this can cause episodes of hypoglycemia. <\/p>\n\n\n\n The timing of insulin is also crucial. A rapid-acting insulin<\/a> is designed to be taken a few minutes before starting a meal. If you forget to take your rapid-acting insulin, it can be safer to skip that dose instead of taking it several hours after the meal. <\/p>\n\n\n\nWhat is Hypoglycemia? <\/h2>\n\n\n\n

To differentiate between the two, take your blood sugar a few times during the night. If blood sugars are high in the early morning hours, it likely isn\u2019t the Somogyi effect. If blood sugars are low in the early morning hours, then high blood sugars in the morning are likely due to the rebound hyperglycemia\/Somogyi effect.
<\/li>\n\n\n\nPrevention of Hypoglycemia <\/h2>\n\n\n\n
Eat Consistently<\/h3>\n\n\n\n
Some people find protein helpful in preventing low blood sugar levels; for example, eating cheese and crackers for a snack instead of just crackers. Eating a very low carbohydrate diet, such as a ketogenic diet, may not be the best choice for someone with chronic hypoglycemia. <\/p>\n\n\n\nTake insulin and medications as prescribed<\/h3>\n\n\n\n
