From hypothyroidism to liver disease, sudden weight gain could be a sign of all these medical conditions

Our weight often fluctuates due to various lifestyle factors such as age, illness, diet, hormones and level of physical activity. Usually, the weight can rise or fall by a few grams or kilos over a span of days. This weight fluctuation can be big over a span of months or years. However, if you notice a sudden or unexpected weight gain in a short period of time, it could be due to an underlying health condition.

An underactive thyroid gland, also known as hypothyroidism, can slow down your metabolism, leading to fluid retention. A reduced metabolic rate also means fewer calories are burned at rest, which can contribute to weight gain.

Hypothyroidism can also cause water retention due to the decreased efficiency of the thyroid hormones in regulating fluid balance in the body. This can lead to temporary weight gain.

The accumulation of fats in the body due to hypothyroidism can also lead to weight gain. Further, people with an underactive thyroid may experience changes in their appetite, which can also lead to an increase in eating and subsequent weight gain.

According to health experts, heart failure, kidney or liver disease can also cause fluid retention in the body. This can lead to sudden rise in body weight.
