If a pregnant traveler does get diarrhea, the best treatment is vigorous oral hydration. That means drinking enough fluids that she has to urinate every two hours and her urine is pale in color. Imodium or Lomotil may be taken if necessary, but Pepto-Bismol is best avoided. Antibiotics should be reserved for cases severe enough to require medical attention.
Sunburn and heatstroke tend to be more severe in pregnancy so sunscreen, shade and a good fluid intake are important. At seaside resorts swimming and snorkeling are fine, but pregnant women should avoid scuba diving. There is no way of knowing a safe depth to dive without running the risk of decompression illness (the bends) in a developing infant.
Finally, while sunning on the beach, she should not lie on the bare sand. In tropical environments there are parasites that live in the sand and can penetrate intact skin. They then cause a very itchy rash that look like a worm crawling under the skin!
In summary:
- It is best not to travel to Mexico while pregnant unless necessary.
- Always stay well hydrated with safe beverages
- Have fun but protect yourself from the dangers of sun and sand.
Safe travels…until next time!
