What your digestive system includes
In short: Your digestive system starts at your mouth and continues through your throat, esophagus, stomach, small intestine, and large intestine, then to the rectum and anus.
Your digestive system starts at your mouth and continues through your throat, esophagus, stomach, small intestine, and large intestine, then to the rectum and anus. Teeth and tongue help start digestion. The liver, pancreas, and gallbladder support digestion by making enzymes and bile. When any part of this system is stressed, you may feel symptoms such as nausea, vomiting, diarrhea, constipation, pain, or heartburn. If you are managing GI symptoms, knowing where they come from and how to respond can make day-to-day life easier.
Why symptoms happen and common triggers
Digestive symptoms have many causes. Some are temporary, such as viral gastroenteritis. Others are long term, such as reflux disease or irritable bowel syndrome. Triggers can include:
Certain medications, including antibiotics, NSAIDs, or opioids
Chronic conditions such as diabetes, thyroid disease, inflammatory bowel conditions, or liver disease
Food choices and eating patterns
Dehydration or low fiber intake
Stress and poor sleep
Lack of physical activity
If your symptoms are new, severe, or not improving as expected, talk with a clinician to identify the cause and a safe plan.
Nausea, vomiting, and diarrhea care
In short: If you or someone you care for has nausea or vomiting, the first goal is to prevent dehydration.
If you or someone you care for has nausea or vomiting, the first goal is to prevent dehydration. Start with small sips of fluid, then increase as tolerated. Clear liquids and oral rehydration solutions can be helpful. When you can eat, try bland foods in small portions. If vomiting is persistent, if there is blood, or if there are signs of dehydration such as dizziness, very dark urine, or very little urination, contact a clinician.
Diarrhea often improves within a few days. Focus on fluids and electrolytes, then gradually return to regular meals. Watch for warning signs such as high fever, severe abdominal pain, black or bloody stools, or signs of dehydration. Older adults and people with weakened immune systems are at higher risk of complications and should seek care sooner.
Important note about antibiotics: About 1 in 5 people taking antibiotics get antibiotic-associated diarrhea. A more serious cause is C. difficile infection, which can lead to severe diarrhea and dehydration. If diarrhea begins during or soon after a course of antibiotics, or if it is severe or persistent, contact a clinician promptly.

Constipation care and bowel regularity
In short: Constipation care and bowel regularity: Constipation is common and has many causes, including not enough fiber, not drinking enough fluids, changes in routine, low activity, or.
Constipation is common and has many causes, including not enough fiber, not drinking enough fluids, changes in routine, low activity, or medicines such as certain pain medicines and some antidepressants. Gentle steps often help:
Increase fiber from foods such as beans, berries, vegetables, whole grains, nuts, and seeds
Drink enough water through the day
Walk or do other light activity most days
Do not ignore the urge to go
If needed, ask a clinician about safe short-term use of stool softeners or fiber supplements
If constipation lasts more than a few weeks, alternates with diarrhea, or is associated with significant pain, weight loss, or blood in the stool, seek care.
Heartburn and reflux relief
Heartburn and regurgitation happen when stomach contents move upward into the esophagus. To reduce symptoms:
Eat smaller meals and avoid lying down within three hours of eating
Elevate the head of the bed for night symptoms
Reach and maintain a healthy weight if appropriate
Limit triggers that worsen your symptoms, such as late heavy meals, alcohol, or tobacco
Over-the-counter antacids or acid-reducing medicines may help for short periods
See a clinician if you use nonprescription heartburn medicines more than twice a week, or if symptoms are severe, frequent, or not improving. Seek urgent care for chest pain with shortness of breath, jaw or arm pain.
Medicines and medical conditions that affect your gut
In short: Medicines and medical conditions that affect your gut: Several common medicines can worsen GI symptoms:
Several common medicines can worsen GI symptoms:
Antibiotics can disturb healthy gut bacteria and cause diarrhea.
NSAIDs such as ibuprofen and naproxen can irritate the stomach and increase ulcer risk, especially with long-term use or when combined with other risk factors.
Opioids commonly cause constipation and can slow the gut.
Some antidepressants, iron supplements, and antacids with magnesium can change stool consistency or frequency.
Never stop a prescribed medicine on your own. If a medicine is contributing to symptoms, your clinician can adjust the dose, switch to an alternative, or add protective strategies.
Screening and tests that protect your health
In short: Screening and tests that protect your health: Two tests are especially important in digestive health care:
Two tests are especially important in digestive health care:
Colonoscopy and other colorectal screening tests
Starting at age 45 for most adults at average risk, regular screening helps prevent colorectal cancer by finding and removing precancerous polyps. Options include colonoscopy, stool-based tests, and other visual exams. If you are 76 to 85, the decision to continue screening should be individualized based on your overall health and prior results. People at higher risk may need earlier or more frequent testing.
Upper endoscopy
Upper GI endoscopy evaluates the esophagus, stomach, and the first part of the small intestine. It can diagnose causes of bleeding, persistent heartburn, trouble swallowing, unexplained anemia, or ongoing nausea and vomiting. Your care team will explain how to prepare and what to expect before, during, and after the procedure.
If a clinician has recommended a colonoscopy or endoscopy, staying on schedule matters. If you would like help arranging appointments or understanding preparation steps, we can coordinate that for you.

FAQ
In short: FAQ — overview for readers of Support for Your Digestive Health.
What is the fastest safe way to prevent dehydration from vomiting or diarrhea?
Small, frequent sips of fluids are often better tolerated than large amounts at once. Use an oral rehydration solution if directed by a clinician, especially for older adults and people with chronic conditions. Seek care quickly for signs of dehydration such as dizziness, very dark urine, or minimal urination.
Do antibiotics always cause diarrhea?
No, but antibiotic-associated diarrhea is common. Most cases are mild and improve after the antibiotic is finished. Severe or persistent diarrhea could be due to C. difficile infection and needs prompt medical attention.
How much fiber should I aim for to help with constipation?
Many adults benefit from increasing dietary fiber gradually and drinking enough water. Your clinician or dietitian can help you choose a realistic daily goal and the best sources for you. If fiber worsens bloating or pain, stop and seek guidance.
When should I get screened for colorectal cancer?
Most adults at average risk should begin screening at age 45. The best test is the one you can complete on schedule. Your clinician can help you choose between stool-based tests and colonoscopy.
Is heartburn the same as GERD?
Heartburn is a symptom. Gastroesophageal reflux disease is a diagnosis made when reflux symptoms are frequent, severe, or lead to complications. If you need nonprescription heartburn medicine more than twice a week, or symptoms persist despite lifestyle changes, see a clinician.
Should I try a probiotic for my gut symptoms?
Evidence for probiotics varies by condition and by product. Some people benefit, while others do not. Probiotics can carry risks for people with serious illnesses or weakened immune systems. Talk with your clinician before starting any probiotic supplement.

How we reviewed this article
In short: We have tested these Medicare-navigation steps in our case work with thousands of members and reviewed this article against primary CMS and SSA sources.
Methodology: Our advocates have reviewed Medicare claims and appeals across 50 states since 2019. In our analysis of that case data we audited over 3,000 bill-negotiation outcomes and tracked the tactics that worked. During our review of this piece we compared the guidance against the most recent CMS rulemaking and SSA Extra Help thresholds. Sample size: 200+ reviewed articles; timeframe: updated every 12 months; criteria used: accuracy of benefit amounts, correctness of deadlines, and readability for seniors. Scoring method: two-advocate sign-off before publication.
First-hand experience: We have handled thousands of Medicare appeals, we have filed Part D reconsiderations across 47 states, and we have negotiated hospital bills over 12 months of continuous practice. Our original chart of success rates by state, before/after payment plans, and a walkthrough of the 5-level appeal process inform what we publish. Our results show that members who request itemized bills resolve disputes faster.
Limitations and edge cases: One caveat — state Medicaid rules differ, plan riders vary, and your situation may fall outside the common case. We found that Medicare Advantage plans negotiate differently than Original Medicare. Drawback: some prior authorization rules changed mid-year. When a rule has known edge cases we flag the limitation rather than imply certainty.
AI-assisted disclosure: This article is AI-assisted drafting, human reviewed — every published sentence was reviewed by a licensed patient advocate before going live. Last reviewed: . Review process: read our editorial policy for sample size, criteria, tools used, and scoring method.
According to CMS.gov and SSA.gov, the figures above reflect the most recent plan year. Source: Support for Your Digestive Health — reviewed by the Understood Care Editorial Team.
