While several eating disorders result in a person, drastically reducing their food consumption, some disorders lead to excess consumption of food. Let us take a look at some of the most common eating disorders:

1. Anorexia Nervosa

Anorexia nervosa is one of the most common and well-known eating disorders. People who suffer from this condition starve themselves to the point that causes severe health issues, including death. Such people have an extreme fear of gaining weight and becoming fat. It generally affects women more than men. People who suffer from anorexia nervosa are constantly obsessed with their weight and believe that they are overweight even if they are underweight. They are constantly occupied with the thought of avoiding certain foods and monitoring their weight.

2. Bulimia Nervosa

Bulimia nervosa is an eating disorder where people have an extreme fear of body fat even if their weight is normal. It is characterized by cycles of binge eating and purging. Bulimia nervosa or bulimia, as it is commonly known, is a severe condition which could even lead to death. People who have bulimia may have no control over food and get into a cycle of eating large amounts of food and purging in an unhealthy way. Those afflicted with this condition may take in extreme measures to avoid weight gain. They may indulge in self-induced vomiting, try harmful medications and even follow extreme diets. Bulimia nervosa is more than just about food; it is a psychological condition where the individual is obsessed with self-image and hence challenging to resolve. Several treatment options could help you treat the condition and overcome it.

3. Binge Eating Disorder

Binge eating disorder is a type of eating disorder where people may eat a large amount of food in a short period. This is a result of having no control over the quantity of food they consume and is often followed by a guilty feeling. If not controlled, binge eating disorder can result in obesity and cause other health issues such as diabetes and high cholesterol levels.

Like any other eating disorder, binge eating disorder results from psychological issues; those suffering from the disorder usually develop it due to depression or stress.

4. Pica

Pica is an eating disorder that makes an individual crave substances that do not offer any nutritional value. People who suffer from this disorder would consistently eat things such as, dirt, chalk, soap, detergent, paint and many other non-food items. Pica can cause serious health issues; individuals suffering from pica might suffer from nutritional deficiencies, infections and poisoning. Pica can affect people from all age groups but is often seen in children and mentally disabled.

Ultimately it depends on the individual; finding the right cause is necessary for fighting it. Let us take a look at some of the most common causes of obesity:

Causes of Obesity

1. Eating too Much

Overeating too often is one of the leading causes of obesity. Junk foods, fast foods and highly processed foods, when eaten over a long period can lead to obesity. Foods rich in sugar and fats tend to increase your weight without providing the benefits of healthy foods such as fruits, vegetables, and whole grains.

2. Genetics

In most cases, obesity can be resolved with lifestyle changes, but if the cause of obesity is genes, it becomes difficult to tackle the problem. Many types of genes contribute to obesity. Such genes usually influence appetite, cravings, metabolism and other factors that dictate the body’s tendency to gain or lose weight.

3. Certain Medications

There are several ways in which medications can cause weight gain. It can increase your appetite, affect your metabolism or get you so tired that you avoid exercising. Medicines that treat depression, diabetes, epilepsy and certain drugs such as steroids may cause weight gain.

5. Poor Sleep

The irregular sleeping hours, and even lack of adequate sleep can cause obesity. It is believed that a minimum of 7 to 8 hours of sleep is required every night to regulate the body’s metabolism and to avoid hormonal imbalances. Such hormonal imbalances can lead to weight gain. Inconsistent sleep can increase your appetite, thereby leading to weight gain.

6. Hormonal Imbalance

Hormones can control the metabolic rate and play a part in the body’s weight gain or loss. Hormonal imbalances can cause significant changes to the body, including its ability to utilise fat.

7. Lack of Exercise

The modern-day lifestyle has resulted in long hours of immobility and encouraged a sedentary lifestyle with little to no exercise. Hours of sitting at the office, followed by a lack of physical activity at home, have increased cases of obesity and other disorders. The consumption of unhealthy foods worsens the situation.

8. Emotional eating

Certain emotions trigger overeating; this is a response to deal with these emotions. Stress, anger and boredom are triggers that could result in excess consumption of food.

9. Medical Conditions

Many medical conditions can lead to weight gain, sometimes even extreme weight gain. Conditions such as Cushing syndrome, osteoarthritis and Poly-cystic ovarian syndrome are some health conditions that could result in weight gain.

10. Parental Approach

The obsession among Indian parents to make their children healthy by feeding them excessive amounts of food is one reason for weight in children in India. This could also lead to obesity and other diseases later in life. At times it leads to obesity in childhood itself. The misconception that a skinny child is unhealthy is the root cause of this unhealthy habit among Indian parents.
