Why Digestion Changes as We Age
Before we explore the specific signs to watch for, it helps to understand why our digestive system might act differently as we enter our 60s, 70s, and beyond. Think of your body as a beautifully complex machine that has been running smoothly for decades. Over time, some of its parts naturally begin to operate at a different pace. This is completely normal and nothing to fear.
Several factors contribute to these changes:
Slower Motility: The muscular contractions that move food through your digestive tract can become a little slower and less forceful. This can sometimes lead to constipation and a feeling of fullness.
Changes in Stomach Acid: For some, the stomach may produce less acid. Stomach acid is essential for breaking down food and absorbing nutrients like vitamin B12, iron, and calcium. Reduced acid can affect how well you digest certain foods.
Medication Side Effects: As we get older, we are more likely to be taking medications for various conditions like high blood pressure, arthritis, or heart health. Many common medications can have side effects that impact digestion, causing anything from constipation and nausea to heartburn.
Weakening Muscles: The muscles of the abdominal wall and pelvic floor can weaken over time, which can affect bowel function. Even the valve that keeps stomach acid from flowing back into the esophagus can become less efficient, leading to more frequent heartburn.
Understanding these natural shifts is the first step. It allows us to have a baseline for what is “normal for me.” When a symptom is new, persistent, and doesn’t fit your personal baseline, it’s time to pay closer attention.
