So much joy, so many worries, so many bodily changes -- your growing belly notwithstanding.

It’s a no-brainer that the stages of pregnancy present a number of challenges, especially in the area of physical health.

In the beginning, you are likely to contend with morning sickness and in later stages you might have concerns about gestational diabetes, to name just a couple of examples.

Many physical complaints, though, center on the everyday workings of the digestive system.

Here are five common gastrointestinal complaints shared by women in various stages of pregnancy:

1) Heartburn, or acid indigestion

Pregnancy and heartburn go hand-in-hand for two reasons, said the website FitPregnancy.

The first is the presence of the hormone relaxin, which slows your digestion. The longer food stays in the stomach, the more acid gets produced. The second reason is that your growing belly is exerting pressure on the stomach and lower esophageal sphincter, priming you for acid reflux.

One tip to try:

Add more soups, smoothies, yogurt, puddings and other soft, liquid-like foods to your diet because they tend to move through your digestive system quicker.

2) Gas and bloating

The surge of the hormone progesterone is relaxing smooth muscle tissue throughout your body, including the gastrointestinal tract. A big meal might take a long time to digest, leading to flatulence, burping and other discomforts.

One tip to try:

Besides keeping a food diary to determine which foods are causing gas, try using wheat bran for added fiber in your diet, suggests BabyCenter.com. Wheat bran is a good insoluble fiber that speeds up the passage of food through your gastrointestinal tract.

3) Constipation

Pregnancy hormones and pressure on the intestinal tract are partly to blame, but it might also be that an “eating for two” mentality has loosened your resolve to eat nutritiously and in proper portions.

One tip to try:

Make sure you are getting enough exercise, the kind that you are comfortable with, as your pregnancy progresses. Good choices include walking and yoga.

4) Hemorrhoids

With the increasing pressure in your abdomen, veins in the lower rectum and anus sometimes swell and become inflamed, bringing on symptoms like itching, pain and blood in the stool.

The National Digestive Diseases Information Clearinghouse says that chances are, hemorrhoid discomfort will go away after childbirth. But if it regularly bothers you or causes excessive bleeding, the area needs to be examined by a doctor.

One tip to try:

Eat more fiber through a variety of fruits, vegetables and whole grains or try an over-the-counter fiber supplement that is safe for use during pregnancy.

5) Frequent urination

Not only is the weight of the baby putting pressure on your bladder, but also your blood volume is increasing, making your kidneys work harder. Constant trips to the bathroom? You might just have to live with it.

One tip to try:

Caffeine might be contributing to the problem; try cutting back to one or two cups of coffee or tea a day.

Throughout your pregnancy, it is vital to express any concerns about your digestive tract, the foods you are eating and your overall well-being to your obstetrician or family doctor.

Symptoms that might seem merely bothersome at first can escalate into bigger issues, and when you are carrying another life, the stakes are too high to ignore those symptoms.
