Type 2 diabetes is often associated with being overweight or obese, but it can also occur in people who are lean.
This might seem surprising, but there are several reasons why lean individuals can develop type 2 diabetes. Let’s explore these causes, based on research, in a way that’s easy to understand for everyone.
Type 2 diabetes happens when the body becomes resistant to insulin or doesn’t produce enough insulin. Insulin is a hormone that helps sugar (glucose) enter cells to be used for energy. When this process doesn’t work properly, sugar builds up in the blood, leading to diabetes.
One of the main causes of type 2 diabetes in lean people is genetics. Research shows that family history and certain genetic factors can play a significant role.
If you have close relatives with type 2 diabetes, your risk is higher, even if you are not overweight. Some people inherit genes that affect how their body processes insulin, making them more susceptible to diabetes.
Another important factor is the distribution of body fat. Even if a person is lean overall, they might have a higher amount of fat around their organs, known as visceral fat. Visceral fat is more harmful than fat stored under the skin and can interfere with how the body uses insulin.
Studies have found that people with more visceral fat have a higher risk of developing type 2 diabetes, regardless of their overall body weight.
Lifestyle factors also contribute to type 2 diabetes in lean people. Physical inactivity can increase the risk of diabetes.
Regular exercise helps the body use insulin more effectively, and a lack of physical activity can lead to insulin resistance. Even lean people need to stay active to keep their blood sugar levels in check.
Diet is another key factor. A diet high in refined carbohydrates and sugars can lead to spikes in blood sugar levels. Over time, this can cause the body to become less responsive to insulin.
Lean individuals who consume a lot of sugary foods and drinks or processed foods may be at higher risk for type 2 diabetes.
Chronic stress is another contributor. Stress can increase the production of certain hormones that interfere with insulin.
When stressed, the body releases cortisol, which can raise blood sugar levels. If stress is constant, it can lead to insulin resistance and eventually diabetes. This is true for everyone, regardless of body weight.
Certain medical conditions can also increase the risk of type 2 diabetes in lean people. For example, some hormonal disorders like polycystic ovary syndrome (PCOS) can affect insulin sensitivity.
Other conditions, such as chronic inflammation or autoimmune diseases, can also disrupt the body’s ability to use insulin properly.
Sleep patterns can play a role as well. Poor sleep or irregular sleep schedules can affect how the body processes glucose.
Research has shown that people who don’t get enough sleep or who have disrupted sleep patterns have a higher risk of developing type 2 diabetes. Sleep is crucial for maintaining overall health, including blood sugar regulation.
Some medications can increase the risk of diabetes. For instance, long-term use of steroids or certain psychiatric medications can affect insulin sensitivity and blood sugar levels. If you need to take these medications, it’s important to monitor your blood sugar and discuss potential risks with your doctor.
Age is another factor. As people get older, their risk of developing type 2 diabetes increases, even if they are lean. The body’s ability to use insulin efficiently tends to decrease with age, making older adults more susceptible to diabetes.
Infections and certain viral illnesses can also trigger type 2 diabetes. Some viruses can affect the pancreas, the organ that produces insulin, leading to insulin resistance. This is a less common cause but still significant.
In conclusion, while being overweight is a well-known risk factor for type 2 diabetes, lean people can also develop the condition due to genetics, visceral fat, physical inactivity, diet, stress, medical conditions, poor sleep, certain medications, age, and infections.
Understanding these causes can help lean individuals take steps to reduce their risk, such as staying active, eating a balanced diet, managing stress, and getting regular health check-ups.
By being aware of these factors, we can all work towards better managing and preventing type 2 diabetes.
