Why does type 2 diabetes make you feel so tired?

The disease of diabetes happens when your blood sugar is excessively high. The term "blood sugar lump" is an alternative designation for blood glucose. The blood sugar level derived from your diet is your primary energy source. Insulin is a hormone produced by the pancreas. It assists in the process of creating energy by allowing carbohydrates from food to get into your cells more quickly. The body occasionally produces too little or no insulin or uses it inefficiently. Following that, glucose continues circulating in your body but does not reach your cells. Over time, too much blood sugar within the body may cause health problems. Although there is no cure or treatment, you can manage it and keep yourself healthy.

As of 2015, 30.3 million Americans, or 9.4% of the population, had diabetes ( Source). One among four Americans was uninformed about his ailment. Diabetes affects one in four persons over 65. 90–95 percent of people with adult diabetes have type 2. A person develops diabetes if his body does not produce enough insulin or has trouble utilizing the glucose produced. High blood sugar is another condition with a similar title, but they are unrelated. Diabetes mellitus is often meant when the word "diabetes" is used.

The typical sugar sold in stores and grocery stores is not glucose. Our cells use glucose, a naturally occurring glucose, as a fuel source. Sucrose, a sugar commonly found in grocery stores, is very distinct from glucose. Berries and fizzy drinks both contain a lot of sugar. Many hormones control the quantity of glucose found in the blood. The brain interacts with one another through substances referred to as hormonal. Insulin is a protein that the pancreas makes. The pancreas produces insulin to connect with other cells every time you eat. The cells are given instructions by this insulin that takes blood sugar.

Types of Diabetes

Do you know how many types of diabetes are there? Here we will discuss about types of diabetes. There are 3 types of Diabetes −

Type 1 Diabetes (Diabetes mellitus)

Type 1 diabetes develops when an individual's immune system attacks the pancreas, which produces insulin. When the pancreas cannot create insulin, glucose cannot reach the body's organs, which depend on sugar for survival. An individual who has type 1 diabetes has to inject insulin every day of his life to remain alive. They must often, several times per day, test their sugar levels regularly.

Most often affecting younger individuals, type 1 diabetes can also affect people of all ages, although it is far less frequent. Type-1 diabetes affects around 1 in 10 individuals who have diabetes.

Type 2 diabetes (Diabetes mellitus)

Compared to type 1 diabetes, type 2 diabetes is an entirely different condition. An individual with type 2 diabetes produces insulin, so either it doesn't function properly in his system or does not produce sufficient insulin to metabolize the sugar. When the pancreas is not working correctly, blood sugar levels (sugar) can reach the body parts that necessitate it.

Diabetes Insipidus − When your body does not have enough ADH or Vasopressin Diabetes Insipidus happens. Hypothalamus produces ADH but pituitary gland stores and releases. It is treatable and need medical attention.

Why does type 2 diabetes make you feel so tired?

When type 2 diabetes is present, poor blood sugar management frequently leads to hypoglycemia, or elevated sugar levels, which can induce weariness, among other indications. Dr Zonszein points out that other factors can contribute to the condition. Due to their high blood sugar levels and excessive urine, some persons, particularly the aged, get dehydration. Dehydration contributes to weariness; according to him, "Kidney illness can also cause it."

Being overweight, having high cholesterol, hypertension, and hyperglycemia are just a few of the founders connected to type 2 diabetes, which is a complicated condition. Psychological issues that can significantly contribute to having "low energy" yet are frequently ignored include sadness, feeling stressed by diagnoses or the intricacy of medical treatment, and anxiety.

Working alongside your medical team to ensure you're correctly treating your diabetes and other diseases is essential to reduce fatigue and the risk of many problems and complications. This includes adopting good lifestyle decisions. Those who lead healthy lifestyles—exercise daily, eat well, drink enough fluids, and use their prescriptions appropriately- feel good. "The people who commonly start to have issues are the people who slightly bit slow with exercise, or they eat, or may not even eat during the day and then overeat at night, and sometimes neglect their meds." The most frequent side effects in untreated people are tiredness and headache.

Suppose you have type 2 diabetes and feel exhausted. One sign of the illness is frequently related to fatigue. There are several potential reasons, ranging from fundamental diseases to problems associated with diabetes. Your vitality may occasionally be sapped by just managing your diabetes regularly. You may experience fatigue if your body lacks the energy to carry out its tasks. Your body's ability to efficiently utilize its primary energy source, sugar, might be compromised by high blood sugar. You could be more likely to experience additional health issues such as renal issues, heart disease, illnesses, and loss of feeling from neuropathic pain, which can all lead to weariness. You can feel worn out while your body struggles to resolve these issues and high glucose levels. Since their bodies must work even harder to do daily tasks when they are obese, individuals routinely experience exhaustion. Being overweight strains your cardiovascular and other systems, leaving you lacking energy.

One common reason for weariness or sluggishness is high or low glucose levels. In both cases, weariness results from an imbalance between a person's blood sugar levels and the amount or effectiveness of insulin being circulated. Even if you had a restful night's sleep, having either high or low blood glucose throughout the day may make you tired. Glucose levels rise if insulin is either insufficient (frequently the case with prediabetes) or not operating as it should.


The inability of the body to properly regulate and utilize sugar (glucose) as a fuel source is the root cause of type 2 diabetes. It is a disorder that lasts for a long time (chronic) and causes excessive sugar in the blood. Problems with the heart, the immune system, and anxiety have all been linked to high blood sugar levels. The pancreas cannot produce enough enzymes to regulate the glucose entering the cells. Because of this, the cells become less susceptible to the effects of diabetes, and as a result, they consume less glucose.
