Ms. Kanikka Malhotra - nutritionist and diabetes educator (India) said that aging can significantly affect digestive function, leading to discomfort and reduced nutrient absorption.
Understanding these changes is key to managing age-related digestive problems and maintaining optimal gut health.
Ms. Malhotra explains that increasing age affects the stomach and its functions, including:
Decreased muscle tone in the intestines: As we age, the muscles in our digestive tract, especially in our intestines, tend to weaken. This causes food to move more slowly through our system, causing constipation or, in some cases, diarrhea. Decreased muscle tone in our intestines can also contribute to discomfort and slow digestion.
Decreased saliva production: Saliva plays an important role in breaking down food and lubricating it for easier swallowing. As people age, saliva production decreases, making it more difficult to chew and swallow food. This can interfere with digestion and nutrient absorption.
Changes in stomach acid production: Older adults often have reduced production of stomach acid, which is needed to break down food and absorb nutrients such as protein, calcium, and vitamin B12. This reduction can cause indigestion, gas, and bloating.
Poor nutrient absorption: As we age, the surface area of our intestines can decrease, along with the efficiency of nutrient absorption. This can lead to deficiencies in essential vitamins and minerals, especially vitamin D, calcium, and iron.
Weakened immune system: Declining immune function with age also makes the digestive system more susceptible to infections, which in turn aggravates gastrointestinal problems.
Bowel Movements: Weakening of the intestinal muscles can lead to slow bowel movements and constipation. The rhythmic contractions responsible for moving food through the digestive tract become less effective, contributing to constipation.
In some cases, weak pelvic floor muscles due to aging can lead to fecal incontinence, especially in older women.
