5 medical conditions that cause weight gain

When you gain weight, you may assume that your lifestyle may be responsible. If you eat more calories everyday without exercise and you are not active, there is a tendency for you to blow up.

Women should know that some health conditions can also influence weight gain by affecting their appetite and energy levels. Unexplained weight gain and fatigue can be caused by an underlying medical condition.

If you are experiencing prolonged weight gain when you don’t to be big, talk to your doctor to run some tests so that you will know if you have some medical conditions.

If you want to know what diseases cause rapid weight gain, look no further, they are outlined below:

Polycystic ovary syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is a hormonal imbalance that can cause irregular periods, infertility, hair growth on the face, and weight gain. It causes weight gain because it is tied to insulin resistance.

Insulin resistance means your body cells don’t respond effectively to insulin, a hormone that helps keep your blood sugar stable. This may cause sudden weight gain in stomach and thighs.

Peptic ulcer disease

If you have peptic ulcer disease, sores appear on the lining of the stomach or duodenum, the first part of the small intestine immediately beyond your stomach.

Peptic ulcer symptoms include pain that begins between meals or during the night, pain that pauses if you eat or take antacids, pain that lasts for minutes to hours, and pain that comes and goes for several days or weeks.

With this medical condition, your eating habits may change in an attempt to deal with the pain associated with it. You can overeat or eat more frequently as that helps with the abdominal pain which can lead to weight gain.


If you suffer from insomnia, you may find it impossible to fall asleep or stay asleep. You might also wake up in the middle of the night and find it hard to go back to sleep.

You may feel tired all the time and have anxiety about sleep. But you may also experience weight gain. You may start getting fat when you take alcohol to help you sleep which has excess calories.

Persistent depressive disorder

Depression can lead to weight gain if people eat more than usual to cope with feelings of emptiness and sadness. If you have depression, you may also have a hard time living a healthy and active life.

This condition is also known as dysthymia and it happens when a person experiences prolonged feelings of sadness. If you have this condition, you may have feelings of guilt, lose interest or pleasure in hobbies, have difficulty sleeping, become irritable and have trouble concentrating

Congestive heart failure

When your heart can’t pump enough blood to meet your body’s needs, congestive heart failure occurs. As a result, blood and fluid can build up in your feet, ankles, and legs, which can cause swelling and rapid weight gain. If you have this medical condition, your abdomen may swell too.


Your thyroid is a small butterfly-shaped gland in your neck. Your thyroid produces the hormones triiodothyronine and thyroxine to control the rate of different activities in your body that make up your metabolism, like how quickly you burn calories.

If your thyroid gland doesn’t make enough of these key hormones, hypothyroidism occurs. This can reduce your metabolism and may cause excessive weight gain in a short period of time.
