What is Polyphagia?

Polyphagia, also known as hyperphagia, refers to an excessive or unusual craving for food. It is usually caused by a desire to consume large quantities of food. Although it is common to experience occasional hunger, polyphagia is marked by persistent and severe sensations of hunger that might not go away even after eating. This condition can indicate underlying health issues and can be linked to a variety of medical conditions, such as diabetes.

Causes and Symptoms of Polyphagia

Many causes can lead to polyphagia, including certain psychological and physiological ones. The most frequent causes are:

1. Diabetes

One of the primary causes of polyphagia is fluctuating blood sugar levels. It occurs especially in people with poorly controlled diabetes, which can hinder the body’s ability to control blood sugar properly. It causes feelings of excessive hunger. The body signals the need to eat to replenish energy reserves, even when food consumption may not address the root cause of the absorption of glucose.

2. Hypoglycemia (Low Blood Sugar)

Low blood sugar levels could trigger a craving when the body tries to bring glucose levels back to normal. If blood sugar levels are too low, your body’s default response is to signal that it’s hungry to trigger eating, which increases blood sugar levels.

3. Hyperthyroidism

An overactive thyroid, also known as hyperthyroidism, can boost metabolism. It results in the body burning energy faster, which could lead to an increase in food cravings as the body attempts to refuel the power it’s using at a rapid rate.

4. Medications

Certain medications, like corticosteroids, antidepressants, and antipsychotics, may increase appetite as a result. The drugs can affect the metabolism or hormones that regulate appetite and result in an increased desire to eat.

5. Psychological Factors

Depression, stress, and anxiety can trigger emotional eating, which can result in an over-eating disorder. This kind of polyphagia is typically psychological since people turn to food as a source of comfort or to deal with their emotions.

6. Pregnancy

A rise in appetite is a typical sign of pregnancy, as the body needs additional nutrition to help support the expanding fetus. It is a normal symptom of polyphagia that is usually temporary and will decrease following the birth.

Symptoms of Polyphagia

The main characteristic of polyphagia is constant and unending hunger even after eating. Other common signs include:

• Continuous cravings: Polyphagia sufferers tend to crave certain food items that are rich in sugar or carbs.
• Trouble feeling full: Even after eating large amounts of food, some may feel hungry.
• Increased weight: Consuming a lot of food may cause the weight to increase over time, particularly when hunger isn’t controlled.
• Fatigue: A routine that involves eating large amounts of food and not satisfying the body’s energy requirements could cause exhaustion or fatigue, particularly when blood sugar levels aren’t appropriately balanced.

Hyperphagia Causes: Why Does Diabetes Cause Polyphagia?

Diabetes is among the leading causes of polyphagia, and the connection between them is extremely complex. The reasons why does diabetes cause Polyphagia are as follows:

1. Impaired Insulin Function

In both type 1 and type 2 diabetes, our body isn’t producing enough insulin, or cells are intolerant to insulin. Insulin is the hormone that assists glucose in entering the body’s cells, which provides energy. If insulin isn’t functioning properly, glucose builds up in the bloodstream; however, cells starve for energy. This is why the body’s signals for hunger are an attempt to replenish the energy needed, even though there’s a lot of glucose in the bloodstream.

2. Inability to Absorb Glucose

In those with uncontrolled diabetes, the cells fail to absorb glucose, even if there is a high blood sugar level. The body can feel hungry as it is unable to absorb the stored energy in the bloodstream. The continuous feeling of hunger is the body’s response to this imbalance of energy.

3. Frequent Urination and Dehydration

The high blood sugar levels cause the kidneys to work more to eliminate excess glucose. This causes frequent urination that can cause dehydration. The body reacts to dehydration by creating thirst and hunger, causing individuals to eat and drink more. This cycle may exacerbate polyphagia.

4. Ketosis in Type 1 Diabetes

In the case of type 1 diabetes, the body doesn’t have enough insulin to handle glucose. It will begin to break down fat into fuel, which leads to an increase in ketones. Ketosis is a normal metabolic process and can also cause an increase in hunger because the body is trying to compensate for the deficiency of glucose usable by obtaining additional energy from food sources.

5. Increased Insulin Resistance

For type 2 diabetics, insulin resistance is a common issue. It’s a frequent problem. The cells in the body are less sensitive to insulin, which means that glucose isn’t quickly absorbed by cells. To make up for this, the body creates more insulin, which could cause an increase in appetite. High levels of insulin within the bloodstream may also trigger the desire to eat, particularly food items that are high in sugars or carbohydrates.

6. Disruption of Hunger Hormones

Diabetes can affect the normal functioning of hunger hormones. Leptin, the hormone that indicates fullness, might not function as it should, and ghrelin, the hormone that triggers appetite, maybe too active. This can make it harder for the mind to manage appetite and satiety, which can lead to an increase in feelings of cravings and hunger.

6 Reasons Why a Diabetic is Always Hungry

For people with diabetes, the constant hunger may be a depressing and threatening sign. Here are 6 reasons why a diabetic is always hungry:

1. Fluctuating Blood Sugar Levels

One of the primary causes of hunger in people with diabetes is the continuous fluctuation in glucose levels. When blood sugar levels are excessively high (hyperglycemia), the body’s cells are not able to make use of glucose as a source of energy. If blood sugar levels fall to a low level (hypoglycemia), then the body sends signals of hunger to bring back the balance. This continuous cycle could create the impression that an individual is never hungry, regardless of how much food they consume.

2. Insulin Resistance

In type 2 diabetes, the body can’t make use of insulin efficiently. As a result, glucose cannot get into the cells for energy, and the body is in constant hunger, which prompts the person to eat more food in the hope of replenishing energy reserves. The cycle of resistance to insulin and hunger can cause it to feel as if the person with diabetes never stops eating.

3. Increased Blood Sugar and Dehydration

A rise in blood sugar levels causes the kidneys to flush out excess glucose through urine, which causes dehydration. Dehydration can cause feelings of hunger since the body seeks out liquids and food to help bring back the balance. This may increase the sensation of constant hunger as it is often mistaken for a desire for food.

4. Medications and Insulin

Certain drugs prescribed to treat diabetes, like insulin or sulfonylureas, may increase appetite as an adverse effect. Insulin, in particular, lowers blood sugar levels by helping glucose get into cells. However, it may cause a feeling of hunger as the body is trying to counter the decrease in blood sugar levels by signaling that it is time to eat more food.

5. Hormonal Imbalance

The regulation of hormones that control appetite. For instance, insulin resistance and the associated elevated concentrations of insulin within the bloodstream may cause increased appetite. In addition, high blood sugar may interfere with the normal functioning of leptin, a hormone responsible for signaling the feeling of fullness, which makes it hard for our body to manage appetite.

6. Fluctuating Energy Levels

Diabetes that is not properly controlled can lead to rapid changes in energy levels. If blood sugar levels are too high or low, it could cause feelings of sluggishness and fatigue, which prompt the body to seek food to boost energy levels. However, even after eating food, those who have diabetes might feel exhausted and search for food as a means to boost their energy levels.

Conclusion

Polyphagia, also known as over-eating, is a common occurrence in patients with diabetes due to problems controlling blood sugar levels, insulin resistance, fluctuations in glucose levels, and dehydration. Managing it involves controlling blood sugar with medication or diet and exercise, as well as taking care of stress and dehydration. If you are constantly hungry, seeking out a medical professional is essential for identifying the reason and preventing complications that can lead to better overall health.
