Appendicitis is an inflammation of your appendix.
The most common symptom of appendicitis is dull pain near the belly button or the upper abdomen (belly). The pain becomes sharp as it moves to the lower right abdomen. Other symptoms can include:
- Loss of appetite
- Abdominal swelling
- Fever between 99℉ and 102℉
Appendicitis is a medical emergency. It almost always requires prompt surgery to remove the appendix. If you are having this kind of pain and believe it’s a medical emergency, call 911.
If an inflamed appendix is not taken care of, it will eventually burst or perforate (get holes in it). This spills infectious materials into the abdominal cavity. This can lead to peritonitis, which is a serious inflammation of the abdominal cavity’s lining (the peritoneum). That can be fatal unless it is treated quickly with strong antibiotics.
Celiac disease is a digestive disorder that hurts the small intestine.
Symptoms
- Digestive discomfort after eating gluten (a protein found in wheat, barley and rye). Not all people with celiac disease have symptoms. Digestive discomfort is most common among children.
- The disease can cause long-term digestive problems and keep you from getting the nutrients you need.
Care
- Gastroenterologists care for celiac disease by prescribing a gluten-free diet. Most people with celiac disease who eat gluten-free feel much better.
- A dietitian can teach you how to stay away from gluten while following a healthy and wholesome diet.
Crohn’s disease is a chronic (or long-term) disease that hurts your digestive tract.
Symptoms
The most common symptoms of Crohn’s disease are:
- Diarrhea
- Cramping and pain in your abdomen
- Weight loss
Care
Doctors care for Crohn’s disease with medicines, bowel rest and surgery. They focus on decreasing the inflammation in your intestines and preventing flare-ups of your symptoms. The goal is to keep you in remission (period of time when a disease is not active).
Irritable bowel syndrome is a common disorder of the large intestine that affects 10–15% of adults in the United States. It causes symptoms without any signs of damage or disease.
Symptoms
IBS usually presents with a combination of symptoms including:
- Repeated pain in your abdomen
- Changes in your bowel movements (diarrhea, constipation or both)
Care
Doctors may care for your IBS by suggesting changes to what you eat. Changes in your diet may include:
- Eating more fiber
- Staying away from gluten
- Following a special diet called the low-FODMAP diet (FODMAPs are types of carbohydrates in foods)
Doctors may guide you to other lifestyle changes, medicines, probiotics and mental health therapies, too.
You may have to try a combination of approaches to see what works best for you.
Your doctor can help you find the right care plan.
Lactose intolerance is caused by lactose malabsorption. This is a health problem where your small intestine makes too little lactase and you can't digest all the lactose you eat or drink. Lactose intolerance may affect your health if it keeps you from getting enough nutrients, such as calcium and vitamin D.
Symptoms
After you have food or drinks with lactose in them (such as dairy products), you may have:
- Bloating
- Diarrhea
- Gas
- Nausea
- Pain in your belly
Care
There are ways to manage lactose intolerance. Changing your diet and limiting or avoiding foods that contain lactose can help. Some people may only need to limit lactose, while others may need to stay away from lactose completely. Using lactase products can help some people manage their symptoms.
Talk with your doctor about changing your diet. This can help manage lactose intolerance symptoms and make sure you get enough nutrients.
The American Cancer Society suggests getting a colonoscopy every 10 years from age 45 to 75. You might start earlier if you have a family history of colon cancer.
Recent studies show that colon cancer screenings in adults ages 45–49 find precancerous growths at rates similar to those in older adults. Early detection is important.
Before a colonoscopy:
- Bowel preparation: You’ll need to follow a clear liquid diet and take a prescribed laxative the night before and the morning of the procedure. This helps make sure your colon is clean for visibility.
- Medication adjustments: Some medications, especially blood thinners and diabetes drugs, may need to be paused or adjusted. Always check with your doctor.
- Fasting: No food or drink (not even water) is allowed on the day of the procedure, except for the prep solution (the laxative mixed with fluid) and a small sip of water for essential meds.
What to expect during a colonoscopy:
- Sedation: You’ll be given a sedative through an IV (into the bloodstream) to help you relax or sleep.
- The exam: A thin, flexible tube with a camera (colonoscope) is inserted through the rectum to examine the colon. It typically takes 20–45 minutes.
- Polyp removal: If polyps or abnormal (not normal) tissue are found, they may be removed and sent for biopsy (further study).
After a colonoscopy:
- Recovery: You’ll rest in a recovery area for about 30–60 minutes as the sedation wears off.
- Results: Your doctor may share early findings right away. Biopsy results take a few days.
- Aftereffects: Mild bloating, gas or cramping is normal. You’ll need someone to drive you home.
- Diet: You can usually resume eating once you're fully awake, unless your doctor says not to.
