What is nausea or upset stomach?

Nausea or upset stomach describes a spectrum from mild abdominal discomfort and queasiness to persistent nausea affecting daily function. It is one of the most common digestive complaints, arising from a wide range of triggers: dietary excess, alcohol, acid reflux, stress and anxiety (through the gut-brain axis), medications, early pregnancy, viral illness, food intolerances, and functional dyspepsia. The gut contains more serotonin receptors than any other organ, making it exquisitely sensitive to emotional and psychological state — nausea frequently precedes or accompanies anxiety, excitement, dread, or significant stress.

Nausea or Upset Stomach: Symptoms & Holistic Approaches | Gyfts

Overall pictureEmerging evidence

Common symptom with several recognised contributing factors

Nausea and upset stomach are among the most frequently reported digestive complaints, with clear links to stress physiology, the gut-brain axis, diet, and illness. Evidence for many supportive approaches is growing, though quality varies across interventions.

When to seek care promptlySome presentations of nausea require urgent professional assessment.
Seek prompt medical attention if nausea is accompanied by blood in stool or vomit, severe abdominal pain with rigidity, persistent vomiting or inability to keep fluids down, or unintentional weight loss. These signs may indicate conditions requiring professional evaluation and should not be managed with self-care alone.
What the research showsEvidence for supportive approaches ranges from preliminary to relatively better-established.
Ginger has a relatively stronger evidence base among complementary options studied for nausea, though overall evidence remains mixed. Contexts studied include motion sickness and pregnancy-related nausea. Probiotics show potential for functional digestive discomfort, though findings are inconsistent. Stress-reduction approaches targeting the gut-brain axis are supported by growing research but remain an active area of study.
The gut-brain connectionNausea is often as much a nervous system response as a digestive one.
The gut contains more serotonin receptors than any other organ and communicates with the brain via the vagus nerve — a pathway implicated in nausea triggered by anxiety, illness, and certain medications. This vagal signalling means nausea can arise or intensify through psychological as well as physiological routes, which is why approaches addressing nervous system state alongside digestive function are increasingly explored in research.
Supportive approaches to considerSeveral complementary and lifestyle strategies may help manage mild nausea.
Dietary adjustments, hydration, ginger-based remedies, mindfulness, and breathing practices are commonly used and generally low-risk for mild, transient nausea. Acupressure at the P6 point has some trial support for nausea relief. These approaches work best alongside, not instead of, professional assessment where symptoms are persistent or unexplained.
Limits of current evidenceMany supportive approaches lack large, high-quality trials.
Much of the research on complementary approaches to nausea involves small samples, short durations, or inconsistent outcome measures. Findings for probiotics and herbal remedies vary by formulation and population. Evidence is sufficient to support informed exploration, but inflated outcome claims should be viewed with caution.
When professional input mattersPersistent or unexplained nausea warrants professional assessment.
Nausea lasting more than a few days, recurring without clear cause, or accompanied by other symptoms should be assessed by a qualified health professional. A GP, gastroenterologist, or registered dietitian can help identify underlying contributors. Complementary practitioners can support wellbeing alongside, not as a substitute for, professional assessment.
