Some Possible Causes Of Sudden Weight Gain?

Are you experiencing sudden weight gain and you are not doing anything wrong?

Well, in that case, I would like to tell you that there are several factors that can cause sudden weight gain.

Normally, weight gain results from an increase in an intake of calories and decrease in physical activity. But many a time, people notice sudden weight gain and are unable to understand the cause of it. Sudden weight gain can be symptoms of some side effect or an underlying condition. Certain prescribed medications, not all can actually make you gain weight. Sometimes drugs can cause weight gain, but in some cases, drugs increases the appetite of an individual and as a result, there is an increase in the intake of calories. If you have been gaining weight after taking several medications, ask your doctor if your medicines could be to blame.

In some other cases, weight gain can be a symptom of some underlying medical condition.

1. Hypothyroidism

The thyroid gland plays an important role in the functioning of the human body and it is located in the front of the neck. The thyroid gland is responsible for making, storing and releasing two hormones – thyroxine and triiodothyronine that are responsible for controlling the metabolism – the way the body uses energy. These hormones play an important part in the body and any fluctuations in its level affect the organs of the body.

Hypothyroidism is a medical condition in which the thyroid gland does not produce enough thyroid hormone that is sufficient for the body. Hypothyroidism is a medical condition and is associated with a wide range of complications. Obesity is one of the complications that is correlated with hypothyroidism.

People from hypothyroidism often complain of sudden weight gain. Multiple studies suggest that obesity and hypothyroidism are two conditions that are linked together Dysfunction of the thyroid gland or inadequate thyroid hormones affects the body weight of an individual. Thyroid hormones regulate the metabolism, thermogenesis, food intake and fat oxidation.

Hypothyroidism is associated with decreased metabolic rate and high body mass index. As a result, in women having hypothyroidism, the prevalence of obesity is increasing as rapidly. Almost all the organs of the body are affected by this disorder and some of the symptoms that occur in patients having hypothyroidism include excessive sweating, constipation, loss of sex drive, muscle ache, brittle nails, pain around the eyes and many more.

2. Cushing syndrome

Cushing syndrome is one of the hormonal disorders that can be caused when there is an prolonged exposure of body tissues to the high levels of cortisol. Cortisol is a hormone which is also known as stress hormone and is made by the adrenal glands.

Cushing syndrome is a rare type of disorder. Most often, Cushing syndrome is accompanied by weight gain and excess hair growth of face, neck, chest, and thighs. Other common symptoms of Cushing syndrome include fatigue, weak muscles, high blood pressure, increased thirst, frequency to urinate, high blood pressure and a fatty hump between the shoulders.

Weight gain along with the redistribution of fat especially on the neck,  face, trunk, and abdomen is the most common symptom of cushing’s syndrome. The weight that occurs in this syndrome is different from the weight gain that is caused by the metabolic disorders.

Weight gain is very common in cushing syndrome and almost 90% of people having cushing syndrome complain of weight gain. Sometimes, cushing syndrome is also accompanied by some cognitive problems such as problems with memory and problems with concentration.

3. Polycystic ovary syndrome

Polycystic ovary syndrome is a health problem which occurs in women and these days the prevalence of this disorder is increasing at a very high rate. Many women are living with polycystic ovary syndrome.

Although polycystic ovary syndrome is associated with a wide range of symptoms, weight gain, excess hair growth and acne vulgaris are the most common or in fact are considered to be the hallmark symptoms of this disorder.

Women having polycystic ovary syndrome often find difficult to lose weight or they experience sudden and an unexplained weight gain.

Polycystic ovary syndrome is a disorder that has an impact on the menstrual cycle, hormones, fertility and the way a woman looks. Polycystic ovary syndrome occurs when the estrogen levels in women become higher than normal and stop the ovaries to release an egg.

Polycystic ovary syndrome is also associated with an increased risk of developing diabetes. And there is no doubt that obesity and development of diabetes are linked to each other. Also, a woman with PCOS has insulin resistance.

Insulin is an important hormone to regulate the glucose level in the blood and any abnormality with the production of this hormone can have a large impact on the body. When there is a lack of insulin in the body, it increases the risk of diabetes mellitus.

4. Depression

Multiple researchers have investigated to understand the relationship between depression and obesity and they found out that there is a strong correlation between the two. Depression is associated with various health conditions, including obesity.

Depression is a serious condition. It is more than just being sad, it has an adverse impact on the mental health of an individual. Depression is a mental health disorder.

Basically, depression begins with stress and when the level of stress increases to a great extent and interferes with everyday activities, it triggers the symptoms of depression.

Stress or depression can contribute to changes in dietary behavior and these changes can cause an increase in weight. Also, various antidepressant pills can also lead to weight gain and increases the risk of developing obesity.

Obesity is a condition of being overweight. Antidepressant pills increase the appetite of an individual and lower the metabolic rate. Another mechanism that supports the relationship between depression and the risk of obesity is that depression decreases the physical activity of an individual and healthy diet, as a result, this triggers the symptoms of obesity.
