Hour 9 Pregnancy Yoga – Adjustments to the Digestive and Urinary System

Adjustments to the Digestive and Urinary System

Pregnancy causes tremendous transformations in the urinary and digestive systems to accommodate the developing fetus and provide for the body’s escalating needs. The changes are necessary to support optimal fetal development as well as maintain the health of the mother. In this chapter, we are going to analyze the transformation experienced by the digestive and urinary systems during pregnancy, and their role in both the mother and developing fetus.

1. Digestive System Adaptations

The digestive system is important in supplying the developing fetus with nutrients and experiences various adaptations during pregnancy to support the rising metabolic needs.

Hormonal Influence

Pregnancy hormones, especially progesterone, greatly affect the digestive system. Progesterone is responsible for relaxing smooth muscles, including those found in the digestive tract. Although such relaxation is needed to enable the expanding uterus to increase in volume, it also results in diminished gastrointestinal motility. Consequently, the food stays in the digestive system for a longer time, which may result in:

Constipation: As a result of impaired motility of the bowels, constipation is common among many pregnant women. This results in bloating and discomfort, and sometimes, hemorrhoids.

Heartburn and Acid Reflux: Relaxation of the lower esophageal sphincter facilitates stomach acid’s movement backward into the esophagus, leading to heartburn, especially frequent in the second and third trimesters.

Compression of the Digestive Organs

With the expansion of the uterus, surrounding organs like the stomach and intestines are compressed, resulting in discomfort and the sensation of fullness or even indigestion following meals despite taking even small amounts of food. In later pregnancy, the expanding uterus can also result in delayed gastric emptying, manifesting as bloating and nausea. 

2. Nutritional Needs and Digestion During Pregnancy

With the escalation of caloric and nutritional demands in pregnancy, the body needs an enhanced amount of certain nutrients like protein, iron, folic acid, and calcium. The uptake of nutrients from food by the body gets better in pregnancy to provide the necessary nutrients for the growth of the developing fetus. The enhanced nutritional demands, however, need to be addressed through a healthy and balanced diet, with special consideration to iron content to prevent anemia.

3. Urinary System Changes

The urinary system also undergoes marked changes to accommodate pregnancy demands, as the kidneys do more to sift through waste products from the mother as well as the fetus.

Increased Blood Flow to the Kidneys

In pregnancy, blood flow to the kidneys is increased, making them better equipped to remove waste products. This is an important adaptation, as the kidneys will remove the mother’s and the developing fetus’s wastes. Because of this, pregnant women urinate more frequently, especially during the early and late phases of pregnancy.

Hormonal Influence on Kidneys

Progesterone hormone relaxes the smooth muscles of the urinary tract, and it can result in urinary retentionor incomplete emptying of the bladder. This increases the risk of urinary tract infections (UTIs), which are more prevalent during pregnancy as a result of this urinary stasis.

Increased Kidney Filtration and Fluid Retention

The kidneys also become more effective at removing waste products from the blood, and this results in more fluid being retained. It results in edema, especially in the feet and legs, which is typical in the later pregnancy stages. Further, as the uterus enlarges, it presses upon the bladder, resulting in more frequent bathroom visits and, in some instances, urinary incontinence.

4. Implications for Prenatal Yoga

The urinary and digestive system pregnancy changes can deeply affect a woman’s comfort and general well-being. Yoga therapists need to keep these adaptations in mind, making adjustments to help alleviate symptoms of:

Restorative, gentle movements to ease constipation and encourage digestion

Pranayama breathing to reduce heartburn and acid reflux

Pelvic floor exercises (such as Mula Bandha) to aid the urinary tract’s health and stabilize the pelvic muscles

Pregnant women also need to be careful not to use poses that compress the abdomen or bladder too much, especially late in pregnancy. Maintaining good hydration, good diet, and conscious breathing while practicing yoga can maximize both digestive and urinary efficiency during pregnancy.

Conclusion

The urinary and digestive system changes of pregnancy are essential to the health of both the mother and fetus. Familiarity with these adaptations is critical to yoga teachers and practitioners so that they can offer supportive practices through adaptive, thoughtful means. By adding strategies to minimize typical discomforts and enhance overall system effectiveness, prenatal yoga can prove a powerful means of coping with these physiological changes.
