i am 42 male, all my lifei have weighed 81kg,in past 2 months i gained weight and gaining. im 98kg now, why

This can be either an increase in muscle mass, fat deposits, or excess fluids

In some cases, weight gain can also occur as a result of developing tumors or other abnormal growths.
Muscle weight gain can occur as a result of bodybuilding, in which muscle size is increased through strength training.

If enough weight is gained by way of increased body fat deposits, one may become overweight.
Overweight is generally defined as having more body fat (adipose tissue) than is optimally healthy.

Being overweight is a common condition, especially where food supplies are plentiful and lifestyles are sedentary.
As much as 64% of the United States adult population is considered either overweight or obese, and this percentage has increased over the
last four decades.

A person generally gains fat-related weight by increasing food consumption and/or becoming physically inactive.
