 Eating too much ginger may cause mouth sores, bleeding risks, nausea and more

Ginger (Zingiber officinale) is one of the most widely used spices in the world, valued not only for its warm, peppery flavour but also for its medicinal qualities. From soothing nausea and easing inflammation to supporting digestion, it has long been part of traditional medicine systems like Ayurveda and Chinese medicine.

However, as with many natural remedies, ginger is not free from drawbacks. While generally safe in small, culinary amounts, consuming ginger in large doses or as concentrated supplements may lead to a range of side effects. Some can be mild and temporary, while others may be more serious for certain groups of people.


The hidden side effects of overeating ginger

1. Gastrointestinal upsetOne of the most frequently reported side effects of ginger is digestive discomfort. According to study published in Nutrients, for some people, it can trigger:

  • Heartburn: Ginger increases the production of stomach acids, which can worsen acid reflux.
  • Bloating and gas: In sensitive individuals, ginger stimulates digestive enzymes so strongly that it causes excessive gas.
  • Diarrhoea: High doses can accelerate the movement of food through the intestines, leading to loose stools.
  • Stomach irritation: When consumed on an empty stomach, ginger may irritate the stomach lining, causing a burning sensation or mild pain.

Those with sensitive stomachs, existing acid reflux, or irritable bowel syndrome (IBS) may notice stronger reactions.2. Mouth and skin irritationAccording to a study published in NCCIH, ginger has a naturally strong, peppery taste that can cause a burning or tingling sensation in the mouth. Some individuals also experience:

  • Mouth sores or irritation if they chew raw ginger too often.
  • Skin rashes or redness when ginger oils or extracts are applied topically.
  • Allergic-type reactions such as itching or mild swelling around the lips and gums.

Topical application of ginger, often used in massage oils or compresses, may be particularly irritating for people with sensitive skin. Diluting ginger oils with a carrier oil before use is strongly advised.3. Blood-thinning effects and bleeding riskGinger has natural blood-thinning properties due to its effect on platelets. While this can be beneficial for circulation, it also means:

  • Increased bleeding risk during surgery or after injury.
  • Longer clotting time, making bruises appear larger or last longer.
  • Potential interactions with anticoagulant drugs such as warfarin, aspirin, or heparin.
  • Individuals with clotting disorders or those who are scheduled for surgery should avoid high-dose ginger and consult their doctor.

4. Blood pressure and heart-related effectsFor some people, ginger can help reduce blood pressure by relaxing blood vessels and improving circulation. According to a study in PlosOne, this effect can become problematic:

  • Low blood pressure (hypotension): In people already taking medication for hypertension, ginger may lower blood pressure too much, leading to dizziness or fainting.
  • Irregular heartbeat or palpitations: Excessive consumption has been linked to rapid heartbeat in sensitive individuals.
  • Increased risk of complications in people with heart conditions, particularly if combined with certain cardiovascular medicines.

This makes moderation important for people with pre-existing heart disease or blood pressure issues.

5. Effects on blood sugarGinger may help regulate blood sugar by increasing insulin sensitivity. However, for people with diabetes, this can sometimes be risky:

  • Hypoglycaemia (low blood sugar): When taken alongside diabetes medications or insulin, ginger can lower blood glucose levels too far.
  • Weakness, shakiness, and dizziness can occur if blood sugar drops suddenly.
  • Difficulty in stabilising sugar levels, especially in people on strict medication regimens.

Diabetics considering ginger supplements should closely monitor their blood sugar and consult a healthcare professional.6. Concerns during pregnancyGinger is often used to reduce morning sickness, and moderate amounts are usually considered safe. Still, caution is advised:

  • According to a study in Committee on Toxicity, supplements and extracts may contain high concentrations of gingerol, which could affect pregnancy differently compared to food amounts.
  • Excessive consumption might stimulate uterine contractions, although evidence is mixed.
  • Pregnant women with a history of miscarriage, bleeding disorders, or complications should be particularly careful.

In general, culinary forms of ginger such as tea or biscuits are safer than capsules or concentrated powders during pregnancy.7. Allergic reactionsAlthough uncommon, some individuals are allergic to ginger. Allergic responses can include:

  • Skin reactions such as rashes, itching, or hives.
  • Respiratory issues, including wheezing, shortness of breath, or nasal congestion.
  • Severe reactions like swelling of the lips, tongue, or throat in rare cases.

Anyone who experiences these symptoms after consuming ginger should discontinue its use and seek medical advice immediately.Disclaimer: This article is for informational purposes only and does not constitute medical advice.
