Causes For Sudden Weight Gain



Pregnancy is one of the leading cause for weight gain in women (mothers) after giving birth. When a woman is pregnant, she is advised to take in more calories (food) to cater for the growing fetus in the womb. It’s medically recommended that a pregnant woman should take in an extra 300 calories which will help in the growth of the fetus and keep her strong and energetic to carry the fetus till delivery period (normally after 9 months).

However, most ladies tend to over eat or consume a lot of calories which will make them gain a lot of weight during and after pregnancy. Remember, it’s easy to gain weight in a short time but it’s a little difficult to lose weight for you to get back to your normal average weight. I would recommend all pregnant and expecting women to consume calories which are enough and medically recommended by professional medical personnel’s. See you doctor for more information and guidelines on your diet when pregnant.


When you always sleep late or you don’t sleep all night, you are most likely to gain weight. Research shows that people who are deprived of sleep tend to put on weight suddenly without their notice. When you don’t sleep enough, your body won’t work to its abilities and sometimes you might have a snack to keep you active and awake all night which in turn will make your body slow down and store fats hence sudden weight gain.

If you don’t sleep enough at night, your body will be physiologically stressed; as a result, fat will be stored more efficiently. Therefore, irrespective of whatever situation you are going through, you need to have enough restful sleep to combat the risk of sudden weight gain.


It has been said many a times that stress makes your body go out of work and when it does, you are most likely to keep the weight. Instead of shading the weight, you will eat to compensate and you will eat comfort foods that are usually packed with more calories than you can burn to help ease stress.

Stress lead to the production of excess cortisol the hormone which stores fat in your body which will eventually lead to sudden weight gain.


Every drug which you take or used to treat a particular disease has its own side effects to your healthy. Among the leading side effect of most drugs is sudden weight gain. Drugs such as antipsychotic drugs, diabetic medications, antidepressants, medications to treat migraines & seizures, corticosteroids, steroids, birth control pills work a little different to cause weight gain, from increasing appetite, altering the way fat is stored to how insulin levels change.

Seek medical advice from your doctor about which medication will be work for you and in case you release a sudden weight gain when on drugs, don’t stop without authorization from the doctor instead go back to him or her and discuss about it.


Hypothyroidism is one of the most common medical condition which causes sudden weight gain. Hypothyroidism is a medical condition in which the thyroid is not active enough, making growth and metal development slower than normal. Thyroid is a small organ at the front of your neck which produces hormones which controls the way in which the body grows and functions.

A deficiency of thyroid hormone will decrease metabolism which causing appetite loss and eventually sudden weight gain.


Menopause is a time when a woman stops menstruating usually at around the age of 50. During this time, some hormonal changes in the body may cause an increase in appetite, which will later lead to weight gain. Women who go through menopause loss estrogen causing their shapes to change and they start gaining weight more in the middle ( around the waist).

However, you shouldn’t give menopause as an excuse for gaining too much weight suddenly. At this age, you are aging and your metabolism is slowing down meaning you can burn less calories than its intake. Your exercising or aerobics has reduced and fat is being stored in your body as a result of too much calories you take than you can burn.

If you are on the right diet of foods with less calories, but still gaining weight around the waist more than your hips and thighs, just know that as a result of menopause when in your 50’s.


When you quit smoking, chances are high that you will turn to food when you have the nicotine craving (desire to smoke). Because you quit smoking, you can’t take any more cigarette, instead you will staff yourself with foods rich in calories. This will lead to sudden increase in weight gain. Live a healthy life by quitting smoking but don’t go for junk foods when the nicotine craves in your body.










You need to eat food which is enough for your body for its proper functioning. When eating, eat at-least 5 small meals a day. When you have only 1 meal a day, it will slow down your metabolism, and when you eat your body is already starved which will force you to eat more than what your body needs.

Don’t skip any meal during the day be it breakfast, lunch, dinner or snacks in-between meals. Eating frequently will give you more energy, make you less hungry, reduces cravings, controls blood sugar levels and most importantly reduces fat storage.

In summary, there are many reasons for sudden weight gain, some of the causes for weight gain can be genetic (children may inherit obesity from their parents), psychological (depression and physical inactivity), physiological (people who socializes more tend to eat more junk food and gain weight).
