To not insult and to be as accurate as possible, we will provide the medical definition of underweight problems. As reported by the CDC (Centres for Disease Control), an underweight person is somebody whose body weight is reflected too low to be healthy. These people have BMI (Body Mass Index) more economical than 18.5, and their body weight is usually smaller than usual by 15% to 20% (Per height and age group).

This BMI is a result of a wide variety of conditions. The CDC lists the following as the main reasons: metabolism issues, genetics, various illnesses (Both physical and mental), drug and alcohol abuse, eating disorders, and simple lack of food. 

It is often the case that being underweight problems are symptoms of a disease. Among the conditions that cause severe loss of weight are: Cancer, hyperthyroidism, TB (Tuberculosis), Type 1 diabetes (Also known as juvenile diabetes), and anorexia nervosa. It’s also worth mentioning that being underweight is also often associated with gastrointestinal and liver damage as these types of issues render a patient unable to absorb an adequate amount of nutrients.

A Further Examination Of Causes

1. Media Coverage (or lack thereof)

While obesity is often mentioned and covered (However inadequately) by the media, the number of risks that come with underweight problems is often completely neglected. It, of course, leads to most people being completely unaware of the dangers that come with the condition, as mentioned above, even though being underweight is linked to fatal diseases just as much as being overweight is. Thinness is often praised and desperately sought after in certain professions. The goal of this article and others like it is to change that situation and to replace ignorance with awareness.

Underweight Problems

It is a well-known and well-documented fact. Approximately 13 percentage of the world’s population lacks the food to lead a healthy lifestyle. That is 795 million people. Admittedly progress is being made as these numbers have been steadily decreasing over the 21st century, but the recent wars in Africa and the Middle-East have made the situation worsen.

3. TB (Tuberculosis.)

Tuberculosis was historically called “Consumption” because of how it left the infected underweight and, therefore, with a weakened immune system. This weakness that was usually caused by loss of appetite led to various organs succumbing to infections. While it has mostly disappeared in the Western world, it certainly goes to show how severe damage can a weakened organism suffers.

Underweight Problems 1

A most severe eating disorder whose cause is yet unknown, anorexia is characterized by the refusal to consume food and a healthy (almost obsessive) desire to remain thin. Patients often use extreme measures to stay underweight such as vomiting and frequent usage of laxatives.

Part of the cause is undoubtedly cultural as it is mostly observed within societies and professions that value thinness. It is also quite prevalent among adolescents and children who, as a result, often deal with growth retardation. It causes severe damage to women as well as contributes to bone density loss and may lead to osteopenia or osteoporosis.

Anorexia Nervosa has also proved to be lethal as it can easily lead to heart damage (Through atrophy of the heart muscle) or even sudden cardiac death.

Secondly, any underweight females have the risk of having a premature birth, giving birth to a baby before 37 weeks. A preterm birth baby is at higher risk when it comes to hearing and sight impairments, impaired growth issues, and cerebral palsy. It’s also worth mentioning that preterm death is, at this moment, the most common cause of death among infants.

Besides, an underweight person is far more likely to suffer from anemia, which in turn will be causing dizziness, headache, and of course, fatigue.

Furthermore, it isn’t all that uncommon for an underweight person to lack the necessary nutrients needed to fight off infections.
