The problems which lead to weight gain after surgery:

Fluid Retention: The major cause for weight gain after surgery is the fluid retention. Water is retained in the interstitial space in your body. This leads to weight gain and causes a bloated look. Fluid retention can take place in few parts of the body or the overall body; for example, swollen feet and hands.

Trauma: The body tissues undergo trauma during surgery. This causes inflammation which can lead to fluid retention. The chances of fluid retention are higher if the surgery is due to any accident.

Stress: Hormonal imbalances occur in the body due to stress. This is responsible for excessive fluid retention. Surgery related stress results in high levels of ADH, which makes the kidneys to store the body water. This can also increase weight gain.

Stagnation: Patients are most likely to do very little work after surgery. This leads to weight gain. Patients are encouraged to do some exercises wards off excess weight and also helps to fight post-surgery depression.
