5 hidden causes of sudden weight gain

Unexplained weight gain occurs when a person’s weight increases without changing their diet or exercise routine. This condition usually occurs when there are some changes in the body.

If your body suddenly gains weight quickly, the cause may be due to the following factors:

Lack of sleep

Long-term sleep deprivation disrupts the hormones that control hunger, making the body hungrier and eating more calories. Some studies have also shown that poor sleep affects the function of regulating blood glucose and reduces insulin sensitivity. This results in weight gain and the risk of obesity. In addition, when tired due to lack of sleep, we often exercise less and tend to choose foods high in sugar and fat.

Quit smoking

The process of quitting smoking is often accompanied by weight gain. The reason is that when you still smoke, the amount of nicotine in cigarettes speeds up the metabolism and suppresses appetite, according to the health website Medical News Today (UK).

When nicotine is gone, quitters are more likely to feel hungry and crave more food. Some research evidence suggests that people who used to smoke heavily tend to gain more weight after quitting.

Heart failure

Heart failure is a common cause of fluid retention, which can lead to swelling and rapid weight gain. For example, people with heart failure may find themselves gaining 2 to 3 pounds (1 to 1.5 kg) in a day. Many people gain as much as 5 pounds (2.5 kg) in a week.

This weight gain is unexplained, meaning there is no change in diet but the weight is still gained. The patient also experiences symptoms such as swelling of the legs, ankles or abdomen, along with shortness of breath, fatigue and persistent cough.

Kidney problems

Impaired kidney function causes the body to retain water and reduces excretory function, leading to weight gain due to water retention. Signs that accompany this condition include swelling of the feet and ankles, fatigue, dry skin, puffy eyes, and little or foamy urine. These are signs that reflect abnormalities in the kidney's ability to filter and remove fluid from the body.

Cirrhosis

Cirrhosis reduces the body's ability to metabolize and eliminate fluids, causing fluid to build up in the abdomen. This results in rapid weight gain and swelling. Patients should seek medical attention if they experience symptoms such as abdominal pain, shortness of breath, or swelling in the legs or abdomen, according to Medical News Today .
