Many people think that eating more food is the only way to gain weight. But in reality, it is not that simple. Various physical, hormonal, and lifestyle factors can also play a role in increasing body weight. So, if you suddenly start gaining weight, it is better not to ignore the matter.
According to doctors, if you gain weight abnormally without any significant changes in lifestyle or eating habits, it may be an indication of some other change in the body. According to experts, if you gain about one and a half to two kilograms in a week or about five percent of your total body weight in a month, you should consult a doctor.
Metabolism decreases with age
With age, the body's metabolism gradually starts to decrease. At the same time, the amount of muscle decreases and the tendency to accumulate fat in the body increases. As a result, many people can gain weight even if they eat the same food as before. Although this is a natural process, its effect is relatively more noticeable in some people.
Hormonal Fluctuations
Hormonal changes at different times of life can affect weight gain-
Adolescence: Weight gain may occur during this time due to rapid growth and changes in the body.
Menstrual Cycle: Many women experience temporary weight gain before menstruation due to excess water retention.
Pregnancy: Weight gain is normal due to the growth of the baby and physical changes during pregnancy.
Menopause: Many women start to gain excess weight due to a decrease in estrogen levels.
Stress and lack of sleep
Prolonged stress increases the level of the hormone cortisol in the body. This helps to store fat, especially in the abdominal area, and can increase the attraction to high-calorie foods.
On the other hand, lack of sleep disrupts the balance of hormones that control appetite. As a result, appetite increases and weight can gradually increase.
Some health problems
Some physical problems can also cause sudden weight gain. For example—
Thyroid hormone deficiency
Insulin resistance
Polycystic ovary syndrome (PCOS)
Water retention or edema in the body
Depression or other mental problems
Apart from this, weight gain can also be a side effect of some medications. Antidepressants, birth control pills, high blood pressure medications, and corticosteroids can play a role in this.
What can be done
If you suddenly gain weight, it is important to first find out the cause without blaming yourself. If necessary, you can get the necessary tests done after consulting a doctor. In addition, some healthy habits can also be beneficial—
Eating less excess sugar and processed foods
Eating a certain amount of food
Walking or doing light exercise for at least 30 minutes every day
Controlling stress through meditation or yoga
Ensuring adequate and regular sleep
Sudden changes in the body can often carry important messages. Therefore, if abnormal weight gain continues for a long time, finding out the cause is the most important step.
