Weight Change – Causes, Treatment

Weight change

change in weight is a serious change in weight. This can mean both weight gain and weight loss in relation to normal weight.


Weight loss or gain can have many reasons and will be presented in the following.

Weight loss

If weight loss is unintentional, i.e. it is not the cause of intentional weight loss through dietfastingstress or sports, the cause may lie in a disease. Also, pathological weight loss itself can lead to anorexia and should be treated medically. See also the article on loss of appetite.

Typical diseases for weight loss can be gastrointestinal infections, diarrhoea, cancer, allergies and worm infections.

Weight gain

Weight gain is usually completely normal due to growth and pregnancy. However, the most common reason for weight gain in the Western world is increased food gain (energy gain) with lower energy consumption through exercise, work and sports. The typical disease representatives are obesity (obesity, obesity).

These diseases, in turn, are responsible for many other diseases, some of which can be fatal. Examples include heart failure, inflammation of the heart muscle, hypothyroidism and diabetes mellitus. Furthermore, weight gain can also occur in some metabolic diseases and hormonal disorders and should be treated by a doctor.

Diseases with this symptom

When to go to the doctor?

A small change in weight is usually not a cause for concern. Especially in women, the weight fluctuates by several kilograms over the course of a month. Also, most people gain some weight over the years. A higher weight, which develops over several years, can be controlled by regular examinations at the doctor and often by a change in lifestyle habits. Rapid increases without apparent cause should be discussed in any case with the doctor, who will initiate the necessary examinations.

The situation is similar with a decrease in weight. Those who have changed their lifestyle are happy about the lower weight. However, anyone who loses weight suddenly and quite quickly without cause should definitely consult a doctor. An at first glance inexplicable weight loss can have various causes and should be treated in most cases.

In any case, the visit to the doctor is indicated if a malaise occurs. Usually the instinct reports that something is wrong. If you no longer feel well, it is best to consult your family doctor first. If necessary, this will be referred to the specialists.

Treatment & Therapy

Depending on the cause, an unusual weight gain or decrease should always be examined more closely by the doctor.

Self-treatment is only advisable if the weight gain or decrease is demonstrably due to increased or low calorie consumption. A lot of exercise and a healthy and balanced diet are particularly successful.

Outlook & Forecast

A change in weight does not necessarily have to have a negative effect on the body. For example, if you want to lose weight or gain weight, you can see by changing your weight whether the project works or not. Therefore, in most cases, a change in weight does not need to be treated.

As a rule, an unintentional change in weight is related to a change in diet. Often this diet is unhealthy for the body, so weight increases. A change in weight can therefore indicate a new eating habit that may arise due to stress or other symptoms. Thus, the affected person can also quickly develop , which is a very unhealthy state for the body. Therefore, when changing weight, the patient should always make sure that the weight remains within a normal range.

However, a change in weight can also occur unintentionally. It is often a sign of a disease of the thyroid gland, this condition should definitely be treated. Treatment is carried out with medication. The weight change can also occur due to hormones that have been artificially supplied to the body.

If the weight change is very strong and starts suddenly, it may indicate another serious problem with the body. In this case, it is necessary to undergo an examination at the doctor. Most of the time, however, the weight change is an intentional symptom.


Obesity and anorexia nervosa usually do not have to occur if the patient eats a normal and healthy diet and moves normally. A healthy amount of exercise can be particularly effective here.

What you can do yourself

In the event of a change in weight, it is very important to find out the cause and take any necessary medication. The doctor or may also order supplements. In addition, a food diary can help maintain control over food intake. For both weight gain and weight loss, it is particularly important that all information is honest and complete. Such a diary typically records when what was eaten and in what quantity.

A healthy and balanced diet plays a central role in weight changes. Food should be rich in vitaminsand and include a reasonable amount of calories. If the weight change is due to a disease of the digestive system, special diets can help reduce symptoms.

If the weight change is due to an eating disorder or other mental health problems directly related to eating, the current mood can also be noted in the food diary. This reflection can help to gain clarity about personal triggers.

In the case of unwanted weight gain, sport and exercise in everyday life are also a good means of self-help. Gentle sports such as swimming are an advantage, as the joints are less stressed in the water. At home, light strength training can also be easily implemented with a fitness band. In case of doubt, however, medical or physiotherapeutic advice makes sense so that the sport does not cause overload.
