What should you consider?
According to doctors, food poisoning includes a special risk group: older adults, pregnant women, infants and young children, people with chronic diseases.
The most common serious complication of food poisoning is dehydration. Due to frequent vomiting and diarrhea, the body loses a lot of water, minerals, salt and it is necessary to take fluids.
Infants, older adults and people with suppressed immune systems or chronic illnesses may become severely dehydrated when they lose more fluids than they can replace. In that case, they may need to be hospitalized and receive intravenous fluids.
Contaminated food can cause dangerous complications such as Listeria or Escherichia coli (E. coli).
