Tanya Haj Hassan, a doctor with MSF, explains the severe effect of malnutrition on the body, which means that serious health risks remain even after food becomes available again, Al Jazeera reports.

“The reality is the problem doesn’t end when the food arrives … malnutrition impacts all aspects of the body’s function,” Hassan told Al Jazeera.

“All of the cells in your body are altered by this. In the intestines, the cells die. That results in issues with absorption, with bacteria. Your pancreas struggles; absorbing fats is difficult.

“Your heart cells become weak and thinned. The connections are impacted, the heart rate slows. These children often die of heart failure, even when they’re being re-fed,” he added.

“They also have life-threatening shifts in salts; these can also lead to fatal heart rhythms. They’re more prone to sepsis and shock,” the doctor said, in reference to oral rehydration salt solutions, which are usually administered to people suffering from malnutrition.

“[Patients can face] low blood pressure, skin lesions, hypothermia, fluid overload, infection, vitamin deficiencies that can affect vision and bone.”
