Couple at the same time stomach pain is likely to be because of food problems, such as food impurity or food poisoning. 1. Unclean food: If a couple eats unclean food such as unwashed greens, fruits, unprocessed animal offal or unclean snacks together, it stimulates the gastrointestinal tract, and when the gastrointestinal tract smooth muscle spasms, it can produce stomach pain. Because both husband and wife eat the same food, so there may be a couple at the same time stomach pain. 2. Food poisoning: If the couple ate poisonous mushrooms or uncooked beans at the same time, resulting in food poisoning, triggering acute gastroenteritis, the gastrointestinal tract will be stimulated by toxins under the spasm, thus causing stomach pain. It is recommended that couples with stomach pain at the same time seek medical attention in time to prevent the condition from being delayed, resulting in serious adverse consequences.
