Symptoms of Nausea, Vomiting, and Diarrhea
Before we dive into the causes, let’s take a moment to understand what’s happening in your body when you experience these symptoms.
- Nausea: This is the uncomfortable feeling that you might vomit. It’s often accompanied by stomach pain, dizziness, and a general sense of unease. Nausea can be triggered by various factors, including certain smells, tastes, or even thoughts.
- Vomiting: Also known as “throwing up,” vomiting is the forceful expulsion of stomach contents through the mouth. It’s your body’s way of getting rid of harmful substances. Vomiting is controlled by the vomiting center in the brain, which can be triggered by various stimuli.
- Diarrhea: This is the passage of loose, watery stools three or more times a day. Like vomiting, diarrhea is your body’s attempt to quickly expel irritants or toxins. Diarrhea occurs when your intestines don’t absorb enough water from the food you eat, leading to watery stools.
14 Causes of Nausea, Vomiting, and Diarrhea
1. Viral Gastroenteritis (Stomach Flu)
Viral gastroenteritis, often called the “stomach flu,” is a common cause of nausea, vomiting, and diarrhea. It’s caused by viruses like norovirus or rotavirus, which inflame your stomach and intestines.
Symptoms usually appear 1-3 days after exposure and can last for 1-3 days. While miserable, viral gastroenteritis is usually self-limiting, meaning it will resolve on its own.
The virus spreads through contaminated food or water, or through close contact with an infected person. That’s why outbreaks often occur in closed environments like cruise ships, schools, or nursing homes.
2. Food Poisoning
Food poisoning occurs when you consume food or water contaminated with bacteria, viruses, or parasites. Symptoms can appear within hours of eating the contaminated food and can be intense.
Common culprits include:
- Undercooked meat, poultry, or seafood
- Raw or unpasteurized dairy products
- Unwashed fruits and vegetables
- Contaminated water
Symptoms can vary depending on the contaminant but often include nausea, vomiting, diarrhea, and abdominal cramps. In severe cases, food poisoning can lead to dehydration and may require medical attention.
3. Bacterial Infections
Bacterial infections like Salmonella, E. coli, and Campylobacter can cause severe nausea, vomiting, and diarrhea. These infections are often foodborne but can also spread through contaminated water or contact with infected animals.
Symptoms usually appear 1-3 days after exposure and can last for several days. In some cases, antibiotics may be necessary. Bacterial infections can be particularly dangerous for young children, older adults, and those with weakened immune systems.
4. Parasitic Infections
Parasites like Giardia and Cryptosporidium can cause prolonged diarrhea, nausea, and vomiting. These parasites are usually waterborne and can be contracted by drinking contaminated water, such as from a lake or a poorly treated pool.
Symptoms can last for weeks if untreated. Antiparasitic medications are usually necessary. Travelers to areas with poor sanitation are at higher risk of parasitic infections, which is why it’s often referred to as “traveler’s diarrhea.”
5. Motion Sickness
Motion sickness is a common cause of nausea and vomiting. It occurs when there’s a disconnect between what your eyes see and what your inner ears, which control balance, sense.
This can happen when you’re traveling by car, boat, plane, or even amusement park rides. Anti-nausea medications and simple measures like focusing on a stable horizon can help.
Some people are more prone to motion sickness than others. If you’re susceptible, try sitting in the front seat of a car, over the wing of an airplane, or in the middle of a boat.
6. Morning Sickness
For many pregnant women, nausea and vomiting are an unfortunate part of the journey, especially in the first trimester. This is often referred to as “morning sickness,” although it can occur at any time of day.
While the exact cause isn’t known, it’s thought to be related to hormonal changes. Small, frequent meals and ginger tea can help manage symptoms. For most women, morning sickness subsides by the second trimester, but for some, it can last throughout pregnancy.
7. Medications
Certain medications, such as antibiotics, chemotherapy drugs, and opioid pain relievers, can cause nausea, vomiting, and diarrhea as side effects. This is because they can irritate the lining of your stomach or alter the balance of bacteria in your gut.
If you suspect your medication is causing these symptoms, talk to your doctor. They may be able to adjust your dosage or recommend an alternative. Never stop taking prescribed medication without consulting your healthcare provider first.
8. Alcohol and Substance Use
Excessive alcohol consumption can irritate your stomach and lead to vomiting and diarrhea. This is often referred to as a “hangover.”
Other substances, such as cocaine and heroin, can also cause these symptoms. Staying hydrated and allowing your body to detoxify are important steps in recovery.
Chronic alcohol use can lead to more serious digestive issues, including gastritis and liver disease. If you’re struggling with alcohol or substance use, seek professional help.
9. Anxiety and Stress
For some people, intense anxiety or stress can manifest as physical symptoms like nausea, vomiting, and diarrhea. This is because your gut and brain are closely connected through the “gut-brain axis.”
Managing stress through techniques like deep breathing, meditation, and therapy can help alleviate these symptoms. Regular exercise and a healthy diet can also help manage stress-related digestive issues.
10. Inflammatory Bowel Disease (IBD)
Inflammatory Bowel Disease (IBD), which includes Crohn’s disease and ulcerative colitis, can cause chronic diarrhea, nausea, and vomiting. These conditions cause inflammation in your digestive tract, leading to a range of gastrointestinal symptoms.
Treatment typically involves anti-inflammatory medications and lifestyle changes. In severe cases, surgery may be necessary. IBD is a chronic condition that requires ongoing management and regular check-ups with a gastroenterologist.
11. Appendicitis
Appendicitis is the inflammation of the appendix, a small pouch attached to the colon. It can cause severe abdominal pain, nausea, and vomiting.
If left untreated, the appendix can rupture, leading to a life-threatening infection. Surgical removal of the appendix is usually necessary. If you experience sudden, severe abdominal pain, especially on the lower right side, seek medical attention immediately.
12. Gallbladder Disease
Gallbladder diseases like gallstones or cholecystitis (inflammation of the gallbladder) can cause nausea, vomiting, and abdominal pain, especially after eating fatty foods.
Treatment may involve dietary changes, medications, or in some cases, surgical removal of the gallbladder. Gallbladder issues are more common in women, people over 40, and those who are overweight.
13. Pancreatitis
Pancreatitis is the inflammation of the pancreas, an organ that produces digestive enzymes. It can cause severe upper abdominal pain that radiates to the back, as well as nausea and vomiting.
Treatment involves hospitalization, pain management, and intravenous fluids. The underlying cause, such as gallstones or alcohol use, must also be addressed. Chronic pancreatitis can lead to long-term digestive issues and may increase the risk of pancreatic cancer.
14. Intestinal Obstruction
An intestinal obstruction occurs when something blocks the passage of food or liquid through your intestines. This can cause severe nausea, vomiting, abdominal pain, and constipation.
Causes can include hernias, tumors, or scar tissue from previous surgeries. Treatment typically involves hospitalization and may require surgery. Intestinal obstruction is a serious condition that requires immediate medical attention.
Home remedies for Nausea, Vomiting, and Diarrhea
1. Ginger
Ginger has been used for centuries to combat nausea, and for good reason! Its active compounds, including gingerols and shogaols, have powerful anti-inflammatory and antispasmodic properties. Here’s how you can use ginger to ease your stomach troubles:
- Ginger tea: Steep fresh ginger slices in hot water for 10 minutes. Sip slowly throughout the day. You can add a touch of honey for sweetness if you like.
- Ginger ale: Opt for a natural version with real ginger, not just artificial flavoring. The carbonation can also help settle your stomach.
- Ginger candies: Suck on these for quick relief when you’re on the go. Look for candies made with real ginger for the best effect.
- Ginger capsules: If you find the taste of ginger too strong, you can try ginger capsules. Always follow the dosage instructions on the package.
2. The BRAT Diet
When you’re dealing with nausea, vomiting, or diarrhea, your digestive system needs a break. The BRAT diet is a time-tested approach to easing back into eating. BRAT stands for:
- Bananas: Rich in potassium, which you may have lost through vomiting or diarrhea. They’re also easy to digest and can help firm up loose stools.
- Rice: Easy to digest and helps firm up stools. White rice is typically recommended as it’s easier on the stomach than brown rice.
- Applesauce: Provides nutrients and pectin, which can help with diarrhea. Make sure to choose unsweetened applesauce to avoid excess sugar.
- Toast: Plain, white toast is easy on the stomach. Avoid adding butter or spreads until you’re feeling better.
These bland foods are gentle on your digestive system and can help firm up loose stools. Remember to introduce these foods slowly and in small amounts. As you start to feel better, you can gradually add other low-fat, easily digestible foods like lean meats, eggs, and cooked vegetables.
3. Peppermint: A Cooling Comfort
Peppermint has natural antispasmodic properties that can help relax the muscles of your digestive tract, easing nausea and stomach discomfort. Try these peppermint remedies:
- Peppermint tea: Steep a peppermint tea bag in hot water for 5-10 minutes. Drink it warm, not hot, to avoid further irritating your stomach.
- Peppermint essential oil: Inhale the scent (don’t ingest!) or add a few drops to a diffuser. You can also try applying a drop or two diluted in a carrier oil to your temples or the back of your neck.
- Peppermint candies: Suck on sugar-free peppermint candies for quick relief. The act of sucking can also help produce saliva, which can aid digestion.
4. Stay Hydrated
When you’re experiencing vomiting or diarrhea, dehydration is a real concern. Staying hydrated is crucial for your recovery. Here’s how to do it right:
- Sip clear fluids slowly and frequently. Water, clear broths, and electrolyte solutions are good choices. Aim for small sips every 15 minutes or so.
- Avoid gulping large amounts at once, as this may trigger more vomiting.
- Try ice chips or frozen electrolyte popsicles if you’re having trouble keeping liquids down. These can be especially soothing if you have a sore throat from vomiting.
- Coconut water is a natural source of electrolytes and can be a good option if you can tolerate it.
Remember, the goal is to replace the fluids and electrolytes you’re losing. Signs of dehydration include dark urine, dry mouth, and feeling lightheaded. If you’re unable to keep fluids down or showing signs of severe dehydration, seek medical attention.
5. Probiotics: Restore Your Gut Balance
Probiotics are beneficial bacteria that can help restore the balance in your gut, especially after a bout of diarrhea. They can also help strengthen your immune system. Here’s how to incorporate probiotics into your recovery:
- Yogurt with live cultures: Choose plain, unsweetened yogurt. Greek yogurt is a good option as it’s higher in protein.
- Kefir: A fermented milk drink rich in probiotics. If you’re lactose intolerant, you can find non-dairy versions made from coconut water or other plant-based milk.
- Probiotic supplements: Consult with your healthcare provider for the right strain and dosage. Look for supplements that contain Lactobacillus and Bifidobacterium strains.
- Fermented foods: Once you’re feeling a bit better, you can try incorporating other probiotic-rich foods like sauerkraut, kimchi, or kombucha.
6. Chamomile Tea
Chamomile tea has been used for centuries to calm upset stomachs. Its anti-inflammatory properties can help soothe the digestive tract and reduce nausea. Here’s how to use it:
- Steep a chamomile tea bag in hot water for 5-10 minutes. You can also use loose chamomile flowers in a tea infuser.
- Drink it warm, not hot, to avoid further irritating your stomach.
- Add a touch of honey if you like, as honey also has antimicrobial properties.
- For an extra soothing effect, try adding a slice of fresh ginger to your chamomile tea.
Chamomile tea is also known for its calming properties. This can be helpful if stress or anxiety is contributing to your digestive issues.
7. Acupressure
Acupressure is an ancient technique that can help alleviate nausea. The P6 (Nei Kuan) point on your inner wrist is particularly effective. Here’s how to find and stimulate this point:
- Locate the P6 point: It’s about three finger-widths below your wrist, between the two large tendons.
- Apply firm, but gentle pressure with your thumb for 2-3 minutes.
- Repeat on the other wrist.
You can also find acupressure wristbands at many pharmacies, which apply constant pressure to this point. These can be especially helpful for motion sickness or pregnancy-related nausea.
8. Lemon
The scent of lemon can help reduce nausea for many people. Plus, lemon contains compounds that can aid digestion. Try these lemon remedies:
- Add lemon slices to water or tea. The vitamin C in lemon can also help boost your immune system.
- Inhale the scent of a freshly cut lemon. Keep a lemon on your nightstand if nausea tends to bother you at night.
- Suck on a lemon slice (if you can tolerate it). You can sprinkle a little salt on the lemon to make it more palatable.
- Try a lemon and ginger tea for a double dose of nausea-fighting power.
- Rest and Relaxation: Give Your Body Time to Heal
When you’re dealing with nausea, vomiting, or diarrhea, your body needs energy to heal. Rest is crucial for recovery.
9. Apple Cider Vinegar
While it might seem counterintuitive, apple cider vinegar can help with digestive issues. It has antimicrobial properties and can help balance your stomach acid. Here’s how to use it:
- Mix 1 teaspoon of apple cider vinegar in a glass of water.
- Sip slowly. You can use a straw to protect your teeth from the acidity.
- If you can’t tolerate the taste, try adding a little honey.
Remember, this remedy isn’t for everyone, especially if you have severe nausea or vomiting. Start with a small amount and see how your body reacts.
