Nausea is a common, uncomfortable sensation that makes many people feel as though they might vomit. What Causes Nausea isn’t always straightforward; sometimes it’s linked to something as simple as eating too quickly, while other times it may signal an underlying health condition. Understanding nausea helps you recognize when it’s mild versus when medical help is needed.
This guide provides clear, medically accurate information about nausea, including its symptoms, common causes, treatments, and remedies. If nausea becomes persistent, severe, or is accompanied by concerning symptoms, our Del Rio emergency room team can provide prompt evaluation and care.
What Is Nausea
Nausea is the uneasy, queasy feeling in the stomach often associated with the urge to vomit. It is a symptom rather than a disease and may arise from many triggers, including digestive disturbances, infections, medications, inner ear imbalance, or stress. Research shows that about 12.5% of adults report nausea in general populations, highlighting how common it is across different causes.
Nausea Symptoms
- A queasy or unsettled feeling in the stomach.
- The urge to vomit or retch.
- Excessive salivation or “mouth watering.”
- Sweating or clammy skin.
- Lightheadedness or dizziness.
Causes Of Nausea
Nausea can arise from a wide range of triggers, ranging from temporary digestive upsets to more serious medical conditions. The body often uses nausea as a warning signal that something isn’t right internally. Below are some of the most common causes.
Gastrointestinal Infections
Gastrointestinal infections, such as viral gastroenteritis or bacterial food poisoning, are frequent causes of nausea. These infections irritate the stomach and intestines, leading to queasiness, abdominal cramps, vomiting, and sometimes diarrhea. The body uses nausea as a protective mechanism to eliminate harmful pathogens.
Symptoms
- Sudden nausea with vomiting.
- Diarrhea or loose stools.
- Stomach cramps.
- Fever or chills.
Early Pregnancy (Morning Sickness)
Hormonal changes during early pregnancy can trigger nausea, commonly referred to as “morning sickness,” although it can occur at any time of day. This is a natural response to increased hormone levels and typically peaks around 7–12 weeks of pregnancy.
Symptoms
- Nausea, typically in the first trimester.
- Vomiting at times.
- Food aversions.
- Fatigue.
Motion Sickness
Motion sickness happens when the inner ear and eyes send conflicting signals to the brain about movement. This sensory mismatch can cause nausea, dizziness, sweating, and sometimes vomiting, often during travel by car, boat, or plane.
Symptoms
- Nausea during transit.
- Sweating and clamminess.
- Dizziness or disorientation.
- Headache.
Medications And Medical Treatments
Certain medications, including chemotherapy drugs, can irritate the stomach or stimulate the brain’s vomiting center. Nausea may occur as a side effect, and it can sometimes be managed by adjusting the dose or using supportive treatments.
Symptoms
- Nausea after taking medication.
- Vomiting during treatment cycles.
- Loss of appetite.
- Fatigue.
Gastroesophageal Reflux (GERD)
Acid reflux occurs when stomach acid flows back into the esophagus, irritating its lining. This can result in nausea, heartburn, and discomfort, particularly after eating or lying down. It’s important to note that GERD can cause nausea, and over time, repeated acid exposure can worsen esophageal irritation and make these symptoms more frequent.
Symptoms
- Burning sensation in chest.
- Nausea after meals.
- Sour taste in mouth.
- Bloating.

Migraine Headaches
Migraines are severe headaches often accompanied by nausea and sensitivity to light and sound. Nausea can occur before or during a migraine and can impact daily activities significantly. The intensity of nausea often correlates with the severity of the migraine episode.
Symptoms
- Intense headache on one side.
- Nausea with light/sound sensitivity.
- Visual disturbances.
- Throbbing pain.
Anxiety And Stress
Emotional stress can trigger nausea by activating the body’s fight-or-flight response. Stress-induced nausea often appears as a queasy feeling in the stomach and may be temporary or recurrent depending on stress levels. This type of nausea can sometimes occur even without any physical illness present.
Symptoms
- Nausea during stressful moments.
- Tension in the abdomen.
- Rapid heartbeat.
- Shallow breathing.
Inner Ear Disorders
Disorders affecting the inner ear, such as vestibular neuritis or Meniere’s disease, disrupt balance and spatial orientation. This can cause vertigo and associated nausea. These symptoms often worsen with sudden head movements or changes in position.
Symptoms
- Feeling off balance.
- Spinning sensation (vertigo).
- Nausea and vomiting.
- Hearing changes.
When To See A Doctor
Persistent, severe, or worsening nausea should prompt a visit to a healthcare professional. Certain warning signs can indicate serious underlying issues that require immediate evaluation.
- Nausea with severe abdominal pain.
- Vomiting blood or dark material.
- Signs of dehydration (dry mouth, dark urine).
- Chest pain or difficulty breathing.
- Confusion or fainting.
If you notice these symptoms, contact the STAT Specialty Hospital right away for medical evaluation.
How To Get Rid Of Nausea
Relief from nausea depends on identifying and addressing its underlying cause. While mild nausea may resolve with simple measures, persistent or severe nausea often requires medical treatment. Lifestyle adjustments and supportive care can significantly improve comfort.
- Antiemetic Medications: Most doctors recommend medicines such as ondansetron or metoclopramide to relieve nausea by blocking signals to the brain’s vomiting center.
- Antacids or Acid Reducers: For nausea caused by acid reflux or GERD, agents like famotidine may be helpful.
- Hydration & Electrolytes: Oral rehydration solutions replace fluids lost through vomiting and help prevent dehydration.
- Motion Sickness Pills: Antihistamines (e.g., dimenhydrinate) are often recommended for motion-induced nausea.
- Medication Adjustments: If a drug causes nausea, your doctor may alter the dose or switch medications.
Nausea Remedies
In addition to medical treatment, natural remedies and lifestyle changes can help reduce nausea. These strategies are often gentle, easy to implement, and can complement professional care.
- Ginger Supplements & Tea: Ginger contains compounds that can calm the stomach and reduce nausea naturally.
- Peppermint Tea: Peppermint relaxes gastrointestinal muscles and eases nausea sensations.
- Small, Frequent Meals: Eating bland foods in smaller portions can prevent overwhelming the digestive system.
- Deep Breathing & Relaxation: Slow, controlled breathing reduces stress-related nausea.
- Cold Compress on Neck/Head: Applying a cool compress can activate the body’s calming response and lessen queasiness.
