Malnutrition is a condition that results from eating a diet not having sufficient nutrients or are too much such that the diet causes health problems. Not having enough nutrients is called undernutrition or undernourishment while too much is called over nutrition. Malnutrition is however used to specifically refer to undernutrition where an individual is not getting enough calories, protein, or micronutrients.

Protein-energy malnutrition and dietary deficiencies are the two main types of undernourishment. Protein-energy malnutrition has two severe forms including marasmus (a lack of protein and calories) and kwashiorkor (a lack of just protein). Common micronutrient deficiencies includes a lack of iron, iodine, and vitamin A.

Giving food to people who need it most, both by delivering food and providing money so people can buy food within local markets are effective.

In 2017, there were 815 million malnourished (undernourished) people in the world. Approximately a third of deaths in children are believed to be due to undernutrition, although the deaths are rarely labelled as such. In 2010, malnutrition was estimated to have contributed to about 1.5 million deaths in women and children. An additional 165 million children were estimated to have stunted growth in 2013. Undernutrition is more common in developing countries and certain groups have higher rates of undernutrition, including women particularly while pregnant or breastfeeding. In the elderly, malnutrtion becomes more common due to physical, psychological, and social factors.

How does Malnutrition affect your body?

Adverse effects of malnutrition include reduced muscle and tissue mass, decreased mobility and stamina, breathing difficulties which can increase the risk of respiratory failure and chest infection. Malnutrition slower the immune response which increases the risk of infection and it will take more time to heal the wound or illness. It also decreases the body temperature which puts a risk of hypothermia. It may make people feel tiredness and can also cause depression.

What are the causes of Malnutrition?

  • Food insecurity-Lack of access to sufficient and affordable food in both developing and developed nations to malnutrition.
  • Digestive problems and issues with nutrient absorption– Crohn’s disease, celiac disease and bacterial overgrowth in the intestines may cause malnutrition.
  • Excessive alcohol consumption– Heavy alcohol drinking can lead to inadequate intake of protein, calories and micronutrients.
  • Mental health disorders– Depression and other mental health conditions can increase the risk of malnutrition.
  • Inability to obtain and prepare foods-Being frail, having poor mobility and lack of muscle strength increases the chance of malnutrition.

How is Malnutrition diagnosed?

Several factors are taken into account to diagnose malnourishment:

In adults body mass index (BMI) is measured to determine if you have a healthy weight according to your height or to know the cause of unintentional lost weight. Other nutrition deficiencies are also taken into account.

Diagnosing malnutrition in children involves measuring weight and height and comparing it against the expected average height and weight for a child of that age. A notable drop below the expected level could indicate a risk of malnutrition.

Blood tests can help to measure protein levels in the blood. If there is low levels of protein in blood then a child is indicated to be malnourished.
