Many people try to control their diet and exercise regularly, but the numbers on the scale do not move as expected. Some lose a little weight and then quickly regain it, leading to frustration and loss of motivation.
In reality, ‘body weight’ does not depend solely on the amount of food consumed but is related to the hormonal system that controls metabolism and energy storage in the body, especially “insulin” and “thyroid hormones,” which play a significant role in weight balance.
In this article, we will explain the differences between these two mechanisms to help understand what causes abnormal weight gain.
‘Diabetes’ and Its Relation to Weight Gain
Diabetes Mellitus (DM) is directly related to the hormone “insulin,” which controls blood sugar levels by helping glucose enter cells to be used as energy.
In individuals with insulin resistance, the body responds poorly to insulin, requiring more insulin production to control blood sugar levels. Therefore, persistently high insulin levels stimulate fat accumulation, especially in the abdominal area.
Those in the prediabetic stage or with type 2 diabetes may find it easy to gain weight and difficult to lose it, even with some dietary control. Additionally, fluctuating blood sugar levels can trigger hunger and cravings, making it harder to control eating behavior unconsciously.
Warning Signs of ‘Diabetes’ to Watch For!
- Increased weight and waist circumference
- Feeling tired after eating
- Frequent hunger or craving sweets
- Elevated blood sugar or HbA1c levels
‘Thyroid’ and Its Relation to Slowed Metabolism
The thyroid gland produces hormones that regulate the body’s basal metabolic rate (BMR). If the body is compared to an engine, the thyroid controls the engine speed.
Hypothyroidism
Metabolism slows down, causing the body to use less energy even if food intake remains the same, leading to easier weight gain. Some may also experience water retention, causing weight gain not solely due to fat.
Common symptoms include
- Easily fatigued, lack of energy
- Feeling cold easily
- Dry skin, hair loss
- Constipation
- Weight gain despite not eating much
This condition can be assessed by hormone levels such as TSH and Free T4.
Hyperthyroidism
The thyroid gland produces more hormones than normal, increasing the basal metabolic rate (BMR).
The body uses more energy than usual, so even with the same food intake, unintentional weight loss may occur. Some may eat more but still lose weight because the body burns energy faster than balanced.
Common symptoms include
- Palpitations, hand tremors, rapid pulse
- Excessive sweating
- Feeling hot easily
- Fatigue or muscle weakness
These conditions reflect hormonal imbalances that may affect the cardiovascular system, bone mass, and blood sugar control if not properly diagnosed and managed.
Differences Between ‘Diabetes’ VS ‘Thyroid’
Although both diabetes and hypothyroidism can cause weight gain, the body’s mechanisms work differently.
Diabetes is related to ‘sugar management and fat accumulation’
While hypothyroidism is related to ‘the speed of energy metabolism’
In some cases, symptoms may be similar, such as fatigue, weight gain, and decreased concentration, making self-diagnosis difficult. Some individuals may have both conditions simultaneously, especially those with immune system disorders.
Therefore, diagnosis should rely on blood tests and medical evaluation, not just symptoms alone.
What Tests Should Be Done When Hormonal Problems Are Suspected?
Common basic tests used for evaluation include
- Fasting Plasma Glucose
- HbA1c
- Thyroid hormone levels such as TSH and Free T4
These tests provide a clearer overview of metabolism and hormonal systems before planning appropriate treatment or weight management.
Don’t Blame Yourself Before Understanding Your Body
Weight gain does not always reflect discipline or behavior because hormones greatly influence metabolism, energy storage, and hunger levels.
Trying to lose weight without knowing the true cause can lead to frustration and loss of motivation. Proper health assessment helps provide targeted and more effective self-care.
Therefore, sustainable weight management does not always start with trying harder but may begin with understanding which system in the body is out of balance, then gradually correcting it appropriately for each individual.
‘Diabetes & Thyroid Can Check’ – More Than Just Numbers for Long-Term Health Stability
Diabetes & Thyroid Can Check is a comprehensive health monitoring and care program for patients with diabetes and thyroid diseases, continuing for one year, requiring regular evaluation by an endocrinologist.
It is not just a general health check package but a care system designed to help chronic patients monitor treatment results, adjust behaviors, and reduce the risk of future complications.
Good chronic disease control is not only about treating symptoms but continuous monitoring to maintain health balance in all aspects of life.
