Bloating during pregnancy is a normal part of the process, but it can be uncomfortable to say the least. You get bloated while pregnant due to the progesterone in your body, which slows down your digestive system, as well as your expanding uterus, which can put pressure on your rectum and lead to gas. You can fight bloating during pregnancy by adjusting your diet and your eating habits as well as by reducing your stress levels. You can also speak to your doctor if your bloating becomes painful or uncomfortable so you can get the right treatment for the issue.
