Constipation is a common issue during pregnancy due to hormonal changes, increased pressure on the intestines, and iron supplements. To manage constipation at 19 weeks pregnant, try increasing your fiber intake through fruits, vegetables, whole grains, and legumes. Stay hydrated by drinking plenty of water and incorporate regular physical activity into your routine. Avoid foods that can worsen constipation such as processed foods and dairy products. If these measures don't provide relief, talk to your healthcare provider about safe over-the-counter laxatives or stool softeners suitable for pregnancy. Additionally, for gas problems, avoid gas-producing foods like beans and carbonated drinks. Eating smaller meals more frequently can also help reduce gas buildup.
