Nausea and Upset Stomach: 7 Causes and Relieve Symptoms

Nausea, or the feeling of wanting to vomit, can be caused by digestive issues, stress, motion sickness, or other underlying conditions. While occasional nausea is normal, frequent occurrences may signal a health problem.

Below, we discuss the top 7 causes of nausea and the best remedies, including medications, home treatments, and foods that help relieve nausea.


1. Digestive Disorders: The Most Common Cause of Nausea

If you frequently feel nauseous after eating, the digestive system is often the root cause. Conditions such as:

  • Gastritis (stomach inflammation)
  • Acid reflux (GERD)
  • Food poisoning
  • Stomach ulcers
  • Irritable Bowel Syndrome (IBS)

These can lead to nausea, bloating, stomach pain, vomiting, and appetite loss. Proper treatment for digestive disorders can prevent chronic stomach issues.


2. Inner Ear Problems and Dizziness-Induced Nausea

The inner ear plays a crucial role in balance and equilibrium. Conditions that affect the inner ear, such as:

  • Ear infections (otitis media, labyrinthitis)
  • Ménière’s disease
  • Hearing loss and tinnitus (ringing in the ears)

These can cause nausea, dizziness, vertigo, and vomiting. If nausea occurs with dizziness or hearing issues, consult an ENT specialist.


3. Motion Sickness: Why You Feel Nauseous While Traveling

Many people experience motion sickness from cars, boats, planes, or amusement park rides. Symptoms include:

  • Nausea and vomiting
  • Cold sweats and dizziness
  • Headaches and fatigue

If you suffer from frequent motion sickness, try over-the-counter nausea medications like dimenhydrinate (Dramamine) or meclizine before traveling.


4. Alcohol and Hangover Nausea: Why Drinking Makes You Sick

Alcohol irritates the stomach lining and disrupts the body’s hydration balance, leading to hangover nausea, vomiting, and dehydration.

Best Foods to Cure Hangover Nausea:

  • Bean sprout soup – Contains aspartic acid, which helps break down alcohol.
  • Dried pollock soup – Rich in methionine and lysine, which support liver detoxification.
  • Bananas and honey – Restore potassium and blood sugar levels to ease nausea.

5. Toxic Buildup and Poor Digestion: How Your Gut Affects Nausea

If waste and toxins accumulate in the digestive system, it can cause nausea, bloating, and sluggish digestion.

Signs of Poor Digestion and Toxin Buildup:

Nausea and bloating
Indigestion and excessive gas
Chronic fatigue and headaches
Heart palpitations and dizziness

Improving gut health with fiber-rich foods, probiotics, and hydration can reduce nausea naturally.


6. Anxiety and Stress-Induced Nausea: How Emotions Affect Digestion

Stress and anxiety slow down digestion, which can trigger nausea, dizziness, and an upset stomach.

Symptoms of Stress-Related Nausea:

Fast heartbeat and palpitations
Cold sweats and dizziness
Hand tremors and pale skin

To prevent stress-induced nausea, try deep breathing, meditation, and a healthy sleep routine.


7. Chronic Kidney Disease and Nausea: A Warning Sign of Kidney Problems

If the kidneys cannot filter waste properly, toxins build up in the body, leading to nausea, fatigue, and loss of appetite.

Kidney Disease Symptoms to Watch For:

Swollen legs and face
Reduced urination
Itchy skin and chronic fatigue

If nausea persists along with other kidney-related symptoms, consult a doctor for kidney function tests.
