Stomach pain in the third trimester is usually caused by improper diet, because the level of progesterone in the body increases after pregnancy, which slows down the peristalsis of the gastrointestinal tract, reduces the digestive ability of pregnant women and makes the gastrointestinal tract more fragile. If you overeat or eat spicy, stimulating, indigestible food, it is easy to cause irritation to the gastric mucosa, and patients will experience stomach pain, bloating and other uncomfortable symptoms. Pregnant women can take oral probiotics, such as Bifidobacterium triptans capsules, to promote digestion. If the pain caused by stomach cramps is severe, scopolamine can be injected intramuscularly for antispasmodic and pain relief treatment. If the symptoms are severe and do not improve, it is recommended to see a professional doctor promptly to give the appropriate medication.
