Does Diabetes Cause Weight Gain? Detailed Guide

Diabetes is a complex condition that, if not treated well, can have various effects on the body. Diabetic people, particularly those with type 1 or type 2, are often seen struggling with weight management, and this leads us to a common question: ‘Does Diabetes Cause Weight Gain?’ Yes, insulin resistance causes the pancreas to release more insulin, and this hormone can store fat, leading to weight gain.

Understanding Diabetes

Diabetes occurs when the body cannot properly regulate blood sugar (glucose) levels. This happens when your body either becomes resistant to insulin (type 2 diabetes) or stops producing insulin altogether (type 1 diabetes).
And when insulin is not working properly, glucose builds up in the blood, leading to hyperglycemia (high sugar). Over time, high blood sugar can cause damage to various organs, including the eyes, kidneys, and even the heart.

Connection Between Diabetes and Obesity

There is a strong connection between insulin resistance and weight gain. In Type 2 diabetes, the body’s inability to use insulin effectively results in higher levels of glucose in the blood. In order to cover this situation, the pancreases produce more insulin, resulting in elevated levels of insulin. Insulin itself is an anabolic hormone, meaning it promotes the storage of fat. So, does insulin make you gain weight? Yes, it can. Elevated insulin levels can cause the body to store more fat, especially in the abdominal area, contributing to weight gain due to diabetes. This creates a vicious cycle, where excess weight leads to even more insulin resistance, worsening the condition.

However, in some cases, particularly in the early stages of diabetes or in response to insulin treatment, weight gain in diabetes can be a side effect. People with Type 1 diabetes may experience weight fluctuations, with weight gain occurring after starting insulin therapy. Insulin can help the body store nutrients and maintain energy, but if not carefully monitored, it can contribute to weight gain due to insulin.

Continuous glucose monitors (CGMs) like Freestyle Libre 2 Plus sensors not only monitor your blood sugar level 24/7 without needing to prick your finger, but they are also compatible with automatic insulin delivery (AID) systems such as OmniPod 5.

Diabetes and Reduced Weight

While many people with diabetes face challenges with weight gain, diabetes can sometimes cause weight loss. This is particularly true for people with poorly managed Type 1 diabetes or in the early stages of Type 2 diabetes when blood sugar is very high. The body starts breaking down fat and muscle for energy because it cannot use glucose effectively. If left untreated, uncontrolled diabetes can result in significant weight loss, muscle wasting, and dehydration. This weight loss is often seen as a result of undiagnosed diabetes or poor blood sugar control.

Diabetes-Related Health Issues and Their Effects on Weight

People with diabetes often have coexisting conditions, such as cardiovascular disease, hypertension, or high cholesterol, all of which can have an indirect effect on weight. For example, medications used to manage these issues, like certain blood pressure medications, statins, or antidepressants, may contribute to weight gain. Additionally, chronic inflammation from diabetes can influence metabolism and fat storage, making weight management even more challenging.

Markers of Diabetes and Weight Gain

The following table outlines key markers of diabetes and their connection to weight gain:

Marker of Diabetes	Effect on Weight
Insulin Resistance	Leads to fat storage, especially around the belly area, and increases weight.
High Insulin Levels	Promotes fat storage and weight gain.
Uncontrolled High Blood Sugar	It can lead to weight loss initially, but may cause fat accumulation once insulin is introduced.
Hyperglycemia	Causes excess energy to be excreted, potentially leading to temporary weight loss.
Medications for Diabetes	Certain drugs, like sulfonylureas or insulin, can lead to weight gain due to insulin.

A report shared by the NIH clearly shows that using sulfonylureas can often lead to weight gain.

Insulin Resistance Signs

Insulin resistance is one of the most important factors contributing to weight gain due to diabetes. Key signs include:

• Increased abdominal fat: People with insulin resistance often store more fat around the abdomen.
• Fatigue: Despite high blood sugar, cells do not absorb glucose efficiently, leading to feelings of tiredness and lethargy.
• Frequent urination and excessive thirst: Elevated blood sugar levels cause the kidneys to work harder, leading to increased urination and thirst.
• Skin changes: Dark patches of skin, called acanthosis nigricans, often appear on the back of the neck, underarms, and groin.

Normal Blood Sugar Ranges and Diabetes Diagnosis

Blood sugar levels are measured in milligrams per deciliter (mg/dL), and they help determine whether a person has diabetes or is at risk. Here are the normal ranges:

Fasting Blood Sugar (before meals):

• Normal: 70-99 mg/dL
• Prediabetes: 100-125 mg/dL
• Diabetes: 126 mg/dL or higher (on two separate tests)

Random Blood Sugar (any time of day):

• Normal: <140 mg/dL
• Diabetes: ≥200 mg/dL (with symptoms of high blood sugar)

Monitoring these levels is essential for managing diabetes and preventing complications, including those related to weight gain.

Preventing and Managing Diabetes:

If you’re concerned about weight gain due to diabetes, a well-rounded approach to managing both your blood sugar levels and weight is crucial. Here’s a complete lifestyle strategy:

1. Diet:

• No GPS rule: Focus on meals with low glycemic index (GI) foods, which help maintain stable blood sugar levels and prevent insulin spikes that contribute to weight gain due to insulin.
• Restrict Carbs: Limit processed and refined carbohydrates (white bread, pasta, sugary snacks), as they can cause rapid blood sugar spikes.
• Focus on lean proteins (chicken, fish), healthy fats (avocados, olive oil), and fibrous vegetables to manage blood sugar and promote fullness without excess calories.

2. Exercise:

• Aim for at least 30 minutes of moderate-intensity exercise 5 days a week (e.g., walking, cycling, swimming). Exercise helps improve insulin sensitivity and aids in weight management.

3. Sleep:

• Ensure 7-9 hours of quality core sleep for each night. Poor sleep is linked to insulin resistance and weight gain, particularly around the belly area.

4. Stress Management:

• Chronic stress can lead to elevated cortisol levels, which can promote fat storage and disrupt blood sugar regulation. Practices like meditation, yoga, and deep-breathing exercises can help manage stress.

5. Medical Monitoring:

• Regular monitoring of blood glucose levels, blood pressure, and cholesterol is critical. Discuss any medication adjustments with your healthcare provider to minimise potential weight gain from medications.

What People Think: Diabetes and Weight Gain

A discussion on Reddit’s diabetes forum sheds light on personal experiences regarding diabetes and weight gain. Many users report initial weight loss due to high blood sugar, but once insulin or other medications are introduced, weight gain due to insulin becomes a common concern. Some participants note that maintaining a balanced diet and regular exercise regimen helps mitigate weight gain, while others emphasize that managing insulin levels and avoiding overeating are key.

In conclusion, does diabetes cause weight gain? It depends on various factors, including insulin therapy, insulin resistance, and lifestyle habits. However, with proper management, including a balanced diet, exercise, and stress control, weight gain due to diabetes can be minimized.
