India is also among the leading countries wherein people are affected by the different types of diabetes. 

Type 1 diabetes and type 2 diabetes are the two most common ones that are prevalent in people. There are a few other variations of this condition like Type 1.5 diabetes or gestational diabetes and even prediabetes that can occur among people depending on certain causes and factors. 

Diabetes is a complicated condition to live with. Originally, the only people who were thought of being diagnosed with this were the older population. However, since the overall prevalence has come down age-wise, the awareness of the nuanced aspects of this condition is increasing. This means that the complications and problems associated with diabetes are coming to light. It is not as simple as maintaining a healthy diet and lifestyle. It is not even as simple as making a few changes and exercising regularly. Almost every aspect of life is affected and needs to be altered upon the diagnosis of diabetes.

Is weight loss a symptom of diabetes?

The simple answer to the question – does diabetes cause weight loss – would be yes. Unexpected weight loss may be an indication of diabetes or some other underlying health condition. Diabetes is a common metabolic disorder that has an impact on how your body utilizes sugar from diet. Diabetes is a chronic disorder that, if unchecked, may lead to a variety of health issues, including nerve damage, hypertension, cardiovascular issues and vision loss. If you have diabetes, your body either produces insufficient insulin or is unable to utilize the insulin that is produced properly. As a consequence, your blood sugar levels increase since the sugar is not transformed into energy but rather remains in your blood circulation. Your body doesn't get the necessary fuel since the sugar lingers in your blood. It starts using fat and muscle as fuel as a consequence, which may cause unexpected weight loss. Type 1 and Type 2 diabetes are the two most prevalent kinds of the disease. Because the immune system targets insulin-producing cells, Type 1 diabetes results in little to no insulin production by the body. Early childhood is frequently when type 1 diabetes first manifests. In type 2 diabetes, the body either produces insufficient insulin or develops an insulin resistance. This kind of diabetes often manifests later in life and is considered to result from both hereditary and lifestyle factors, including being overweight and sedentary.

Link Between Diabetes & Unexplained Weight Loss

Therefore, it finds a way to compensate by creating energy by burning fat and muscles rapidly. This causes weight loss. Also know about Indian diabetes diet.

Type 2 Diabetes Unexplained Weight Loss

Various illnesses bring certain consequences along with them. Fluctuations in weight are seemingly common, but if they are sudden and significant, they can be a sign of an underlying problem. If you have experienced sudden weight gain or weight loss, it could be a sign of diabetes or prediabetes. Experiencing unexplained weight loss in diabetes can be your first sign that something is wrong and you should contact your doctor immediately. So what causes weight loss in diabetes? Let’s find out. 

Insulin is a hormone that enables your body to utilize glucose (sugar) as fuel.  When you have Type 2 diabetes, your body does not utilize insulin properly and cannot deliver glucose to your cells. Instead, it accumulates in your blood causing insulin resistance.  When glucose does not reach your cells, your body believes it is hungry and seeks a means to compensate. It generates energy by rapidly burning fat and muscle which is how diabetes causes weight loss. Your kidneys will also start working extra hard to remove the excess glucose in your blood. This consumes more energy and might harm your kidneys.

Type 1 diabetes follows a similar path, but instead of being unable to utilize insulin, your body ceases production entirely. Unexpected weight loss may occur in patients with Type 2 diabetes, although it is more prevalent in people with type 1 diabetes. Unexplained weight loss can be detrimental to health.
