why does hunger occur in patients with uncontrolled diabetes

Polyphgia is a medical term often used for increased appetite or increase in hunger. Polyphagia is one of the three main signs of diabetes, the others being polyuria (excessive urine) and polydipsia (excessive thirst). It is normal to eat more after a strenuous workout as the body cells have utilized energy and the body needs to replace it. People also eat too much when they are under mental stress. Diabetics are also known to have uncontrollable hunger or frequent hunger pangs. This makes them eat more food at every meal. Thus even after eating a heavy meal, a diabetic person may feel hungry within few hours. Polyphagia is often observed in people with uncontrolled diabetes. Diabetes is a metabolic disorder characterized by abnormal increase of sugar in the circulating blood. A person suffering from diabetes, especially when the blood sugar is uncontrolled for a long period has increased appetite. They eat in excessive and frequently as they feel hungry more often. To understand polyphagia associated with diabetes, we must understand the basics of diabetes, a chronic metabolic condition.


In a healthy individual the food that he consumes turns into glucose and provides energy to every cell of the body. Glucose is a fuel for the body cells which allows them to functions well. However, the body cells cannot absorb glucose alone. Glucose needs a companion to facilitate its absorption. This companion is known as insulin, a hormone secreted by pancreas. In diabetes there may be two reasons for insufficient glucose absorption. Either insulin is not produced sufficiently by the pancreas or the cells are resistant to absorb insulin. In both this condition glucose remains unutilized and gets accumulated in the circulating blood. Although glucose is sufficiently available, the body cells remain starved as glucose does not reach to its destination that is the cells. As a result the brain perceives that the cells are starved and sends message to the appetite centre to trigger hunger. Hormone leptin comes into picture and it stimulates the appetite center present in hypothalamus part of brain.


This is how a diabetic person may feel hungry even if there is sufficient glucose circulating in the blood. How To Control Polyphagia In Diabetics? If you feel hungrier even after eating your regular meal then the first thing that you should do is to consult your doctor. He will test your blood sugar for diabetes. Polyphagia or increased hunger is one of the hall mark sign of diabetes. It usually occurs in people with uncontrolled high blood sugar. So a good control of blood sugar is the main factor to control polyphagia. In order to utilize the extra sugar patient has to increase his physical activity. Being active rather than living a sedentary lifestyle will help in reducing hunger pangs to a great extent. Also whenever patient feels hungry he should eat food that has more fibers. Vegetables and fruits contain fibers. Change in lifestyle and taking ant diabetic medicine regularly as recommended by the doctor are key for managing optimal level of blood sugar in diabetics.

Diabetes can cause high blood sugar, and high blood sugar can give you the munchies. So diabetes doesn t, by itself, make you hungry. It s the high blood sugar that can come from out-of-control diabetes that does. Which is crazy, if you think about it. For the most part, the human body does a really great job of maintaining a stable state using a process of small adjustments and counter-adjustments called homeostasis. In the case of blood sugar, the body normally keeps the sugar level just right by balancing little squirts of insulin from the pancreas with little squirts of sugar from the liver. If the liver is running low on its sugar stores your body will give you an advanced head s up that you need to refuel by sending out hunger signals. Where things get weird is that if your blood sugar is already high, the last thing you need is more sugar (in the form of food), right? But in fact, high blood sugar does cause hunger, even though you do not need more food. This is caused largely by a miss-communication within the body s sugar homeostasis system.


Every cell in your body relies on sugar from the blood for food, but they need insulin to get to the sugar. It s insulin that moves sugar from the blood to the cells. If there is not enough insulin, or if it isn t working very well, sugar piles up in the blood while at the same time, it s not getting into the cells where it s needed. Being in a state of high blood sugar is sort of like starving to death in the Chef Boyardee warehouse because you don t have a can opener. The cells don t really realize that there is a ton of sugar just beyond their membranes; all they know is that they are not getting any and so they send out the message: let s eat! The body doesn t really know there is a ton of sugar in the blood either, so it sends the cells signals to the brain: let's eat! Perversely, the higher the blood sugar goes, the louder the signal can become. High blood sugar gives you the munchies, so you eat, which causes your blood sugar to go even higher, which causes more munchies, which
