How Your Digestive System Changes with Age
Just like our joints might feel a little stiffer or our eyesight might not be as sharp, our digestive system also undergoes natural changes as we get older. Understanding these shifts can help you recognize what’s normal for you and what might be a sign to check in with your doctor.
One of the most common changes is a general slowing down. The muscular contractions that move food through your intestines, a process called peristalsis, can become less forceful. This can lead to food spending more time in your digestive tract, which sometimes results in constipation—a very common concern for seniors.
Your stomach may also produce less acid. While this might sound like a good thing, stomach acid is crucial for breaking down food and absorbing vital nutrients like vitamin B12, iron, and calcium. It also helps protect you from harmful bacteria. Lower acid levels can sometimes lead to feelings of indigestion or bloating.
The community of friendly bacteria in your gut, known as the microbiome, can also change. This delicate balance of microbes plays a huge role in digestion, immunity, and even your mood. Shifts in this community can affect how well you process certain foods and can sometimes make you more susceptible to digestive upset.
Lastly, medications can have a significant impact. Many common prescriptions for conditions like arthritis or high blood pressure can have side effects that affect the stomach, from nausea to constipation. It’s always a good idea to discuss how your medications might be impacting your digestive health with your doctor or pharmacist.
