Stress, both acute and chronic, can lead to sudden weight gain. When you're stressed, your body produces cortisol, a stress hormone that can lead to increased appetite and cravingsfor high-calorie comfort foods.

This can cause weight gain, particularly, around the abdomen. This sudden weight gain is not only frustrating but it can also increase the risk of heart diseases. Image courtesy: Adobe Stock

Sleep is crucial for maintaining a healthy body weight. A consistent lack of sleep can disrupt your body's hormonal balance, particularly hormones that regulate appetite and metabolism. Ghrelin, a hormone that stimulates hunger, increases when you're sleep-deprived, while leptin, the hormone that signals fullness, decreases. This imbalance can lead to overeating and weight gain over time. Image courtesy: Adobe Stock

Antidepressants and steroids

Certain medications, such as antidepressants and steroids, can contribute to sudden weight gain. Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), canlead to increased appetite and a reduced ability to feel full, which can result in overeating and weight gain. Steroids, on the other hand, can cause fluid retention and an increase in body fat. Image courtesy: Adobe Stock
