Inflammatory bowel disease (IBD) flares and gastroenteritis incidences increase with heat waves, according to research. The findings come from Swiss researchers explaining, “There is evidence for an increase of IBD hospital admissions by four to six percent for each additional day within a heat wave period. Presence of a heat wave was estimated to increase the risk of infectious gastroenteritis by four to seven percent for every additional day within a heat way period. In the control group, there was no evidence for a heat wave effect.”
The researchers studied 738 IBD patients and 786 infectious gastroenteritis patients over a five-year period. Their data were compared to other non-infectious chronic intestinal inflammations, as the control. During those five years, 17 heat waves were identified.
Lead author Dr. Christine N. Manser said, “The evidence of patients with IBD having a significant increase risk of flare-ups compared to the control group shows a cause and effect between the climate and the disease. This study ties heat stress to digestive symptoms supporting the observed seasonal variation in the clinical course of inflammatory bowel disease and suggests that microbial infections of the gut might be additionally influenced by climate changes.”
“Heat waves are known to cause physical stress as evident from increased frequencies of other stress-dependent health events such as heart attacks. Physical as well as mental stress has been shown to cause flares of IBD, and may explain the increase in IBD hospital admissions during heat waves. During a heat wave, patients with IBD should be aware that there is an increased risk for a flare and contact their gastroenterologist in cases of an increase of stool frequency or abdominal pain. The public should know that a sudden onset of abdominal pain and diarrhea during or shortly after a heat wave might be symptoms of an infectious gastroenteritis,” Dr. Manswer concluded.
Get familiar with these five tips for the prevention of heat-related illness, and you’ll know exactly what to do during a heat wave and how to treat heat exhaustion.
You can also use water to cool yourself down – take cool showers or baths if you need to get some heat relief.
If you experience symptoms like heavy sweating, weakness, fainting, nausea or vomiting, a fast, weak pulse, or cold, pale, and clammy skin, the CDC recommends moving to a cooler location, lying down, loosening your clothing, applying cool and wet cloths to your body, and sipping water.
If you continue vomiting, seek medical help. And if you experience more serious symptoms like a body temperature above 103F, a rapid and strong pulse, possible unconsciousness, or hot, red, dry, or moist skin, call 911. If you are with another person with these symptoms, call emergency service, then move them to a cooler environment and use cool cloths or a bath to reduce the body temperature, but do not give fluids – wait for help to arrive.
