In the fourth month of pregnancy when bloating occurs, first of all, we should pay attention to observe whether the bloating is serious, if it is not serious, then consider the physiological manifestations. During pregnancy, the peristaltic function of the gastrointestinal tract is weakened due to the influence of hormonal secretion in the body, which can cause the phenomenon of distended stomach. During this period, try to pay attention to a light diet, do not eat too greasy food and spicy stimulating food, to avoid aggravating the symptoms of bloated stomach. However, it is also possible that overeating or eating too greasy food that is not well digested can cause the phenomenon of bloating, so you can take some medication to help digestion. During pregnancy, try to choose drugs that have less impact on the fetus, you can choose probiotics or Mamma’s Aid for treatment. During this period, you can also gently massage your abdomen, which can promote gastrointestinal motility to help digestion and relieve bloating.
