Unexplained weight gain: what might be the potential factors?

Several factors can be behind unexplained weight gain:

Hormonal imbalances

The endocrine system plays a key role in weight management. Even a minor imbalance can affect fat storage and energy expenditure.  

• Hypothyroidism: Insufficient production of thyroid hormones slows down the metabolism, leading to gradual weight gain, severe fatigue and sensitivity to the cold. 

• Polycystic ovary syndrome (PCOS): This hormonal disorder affects many women and is often accompanied by weight gain that is resistant to dieting. 

• The menopause: During this period, the drop in oestrogen levels leads to a redistribution of fat towards the abdomen, as well as a reduction in muscle mass.

Metabolic disorders

An unbalanced metabolism can lead to excessive fat storage, even without any change in diet. 

• Insulin resistance: The body is no longer able to use glucose properly, leading to weight gain and an increased risk of type 2 diabetes. 

• Type 2 diabetes: Poorly controlled blood sugar levels can contribute to weight gain. 

• Metabolic syndrome: This syndrome encompasses several risk factors (abdominal obesity, high blood pressure, high blood glucose levels, etc.) that contribute to weight gain.

Psychological factors and stress

• Sleep disorders: A lack of sleep or sleep disorders such as sleep apnoea can disrupt the production of hormones that regulate appetite (ghrelin and leptin) and increase cravings for sugary and fatty foods. 

• Chronic stress: Chronic stress increases the production of cortisol (hypercortisolism), a hormone that promotes fat storage, particularly around the abdomen.

• Anxiety and depression: Mood disorders can influence appetite and fat storage.

Certain medicines

Certain medications can affect your weight, including antidepressants and anti-anxiety drugs, corticosteroids, beta-blockers and hormone replacement therapy.

Water retention

Excessive water retention can manifest as rapid weight gain and swelling in certain parts of the body.

Digestive problems

Digestive disorders such as irritable bowel syndrome or gut dysbiosis can lead to bloating and weight gain. A depleted gut microbiota also promotes insulin resistance and fat storage.

Certain chronic conditions

Certain chronic conditions, such as Cushing’s syndrome, heart failure or kidney problems, can be linked to unexplained weight gain.

Lifestyle factors

Although less ‘unexplained’, certain subtle lifestyle changes can contribute to gradual weight gain, such as a more sedentary lifestyle, excessive consumption of processed foods or sugary drinks, frequent snacking, or alcohol consumption.

If you’re experiencing unexplained weight gain, it’s essential to consult a healthcare professional to rule out any underlying causes.
