Malnutrition is an imbalance in micro and macronutrients —either a deficit or surplus of them— which impedes the body’s capability of growing and staying healthy. As mentioned in previous articles, malnutrition can be caused by several different factors, which include but are not limited to disease, lack of access to safe drinking water, eating disorders, mental health illnesses, and even climate change. With such a wide range of causes, it is expected that the effects of malnutrition are just as varied.

As described on Livestrong.com, malnutrition occurs in stages. The imbalance in nutrients first shows in blood and tissue, followed by metabolic processes —finally, tell-tale signs and symptoms appear. The effects of malnutrition include: changes in body mass, poor wound healing, severe weight loss (cachexia), and organ failure —among others—, all of which are described below.
—Kidneys: Malfunctioning kidneys can cause failure in the regulation of salt and fluid, which in turn can trigger over-hydration or dehydration.
—Brain: Mental health illnesses can cause malnutrition and malnutrition can be a decisive factor in the development of mental health illnesses, such as apathy, depression, introversion, self-neglect and deterioration in social interactions.
—Reproduction: Reduced fertility and a poor sex drive are other effects of malnutrition. Moreover, malnutrition during pregnancy can make the baby more prone to disease, strokes and developing diabetes later in life.
—Impaired temperature regulation: Especially seen in people with cachexia, people who endure severe weight loss due to undernutrition find themselves unable to store body heat, which can lead to hypothermia.
There is no doubt that the effects of malnutrition can be severe –and even deadly—for the population at large. However, this issue is worse yet for newborns, small children and pregnant women. As said by MotherChildNutrition.org, “beyond the age of 2-3 years, the effects of chronic malnutrition are irreversible”. This implies that malnutrition in children must be tackled before they turn two years old, or the future of that child may be impaired.
Statistically, children who are low-for-age or constantly experience weight loss are affected in the long term, namely by not reaching their optimum size and physical capacity as adults. Also, malnourished kids make sickly men and the illness also affects their mental capacity, with undernourished children typically having lower IQs than their well-fed counterparts.
Furthermore, acute malnutrition is the biggest contributor to under-five mortality. This is caused two of the effects of malnutrition: susceptibility to infections and a slow recovery from illness. Finally, undernourished mothers not only give birth to undernourished children, but are at a higher risk of perishing during or after the birth. Malnutrition causes issues such as obstructed labor and postpartum haemorrhage, with anemia –one of the effects of malnutrition— in mothers being linked to increase mortality at labour.
