side effects of kiwi fruit

(1) Oral Allergy Syndrome

Oral Allergy Syndrome is an allergic reaction that can cause mild to severe symptoms when eating certain fruits, vegetables, and nuts. Kiwi fruit is one of the most common foods associated with this condition. Symptoms may include itching or swelling in the mouth, throat, and tongue as well as hives on the skin.

In some cases, a more serious reaction such as difficulty breathing or facial/throat swelling may occur, which requires immediate medical attention.

Treatment for kiwi allergy varies depending on the severity of the reaction and it is recommended to avoid the consumption of the food altogether if known allergies are present. As cross-reactivity between other fruits and vegetables is possible, individuals should consult their doctor about available treatments to manage their symptoms.

(2) Allergic Reactions

Kiwi can lead to allergic reactions due to food allergies, which are caused by the body’s immune system response. This type of reaction is referred to as kiwi allergy and typically occurs when proteins in the fruit are mistaken for harmful substances. Potential symptoms include hives, skin rash, breathing difficulties or wheezing, abdominal pain, and vomiting.

Anaphylaxis, a life-threatening reaction, may occur if not treated immediately with epinephrine. Food sensitivity and intolerance may also arise from eating kiwi, although they do not usually involve an immune system response.

Symptoms such as bloating, diarrhea, or constipation may be experienced if these conditions are present. Individuals who experience any symptoms after consuming kiwi should consult a medical professional to determine whether there is a food allergy or sensitivity involved.

(3) Digestive Issues

Kiwi consumption has been associated with digestive issues such as stomach cramps, bloating pain, and constipation relief. Studies have also suggested that the fruit can be beneficial in relieving diarrhea remedy and providing irregular bowel movements. Additionally, research has indicated a connection between kiwi intake and digestion problems, including indigestion discomfort and gas discomfort.

Moreover, some studies have found that it may provide nausea relief and potentially prevent vomiting. Consequently, it is essential to monitor one’s body reaction when trying new foods or altering dietary habits.

(4) Skin Irritation

Kiwifruit can cause digestive issues as well as skin irritation. Symptoms of skin irritation include itchy skin, rashes, redness, dryness, and occasional allergies. In some cases, people who are sensitive to kiwifruit may experience small bumps, inflammation, discoloration, or general sensitivity in affected areas.

These symptoms usually go away after a few days, but if they persist for longer than two weeks medical advice should be sought. It is also important to check with a physician regarding any medication that could interact negatively with kiwifruit compounds. Taking these considerations into account will help ensure safety when consuming this fruit.

(5) Interactions With Medication

Kiwi consumption can have potential interactions with certain medications and drugs, which may result in various side effects. Large amounts of kiwi may reduce the effectiveness of some drugs including antibiotics such as ciprofloxacin and anticoagulants like warfarin. Therefore, it is suggested that individuals taking prescription medication should consult their healthcare provider before having significant quantities of kiwi regularly.

Furthermore, even small amounts of kiwi can lead to adverse reactions when combined with certain types of drugs, such as antihistamines, antibiotics, diuretics, asthma medications, sedatives, antidepressants, cholesterol medicines, and blood pressure medications. To avoid any unwanted drug-kiwi interactions, awareness of these potential interactions is important before consuming kiwi.

(6) Blood Sugar Changes

Research has found that kiwi consumption may cause fluctuations in blood sugar levels due to their high natural sugar content. However, these fruits are rich in vitamins C and E, potassium, folate, lutein, and other nutrients which have been associated with helping maintain stable and healthy blood sugar levels.

While consuming a large amount of kiwi or eating it on an empty stomach could result in a sudden spike in blood sugar for some individuals, moderate intake should still be encouraged as part of a balanced diet to effectively manage blood glucose levels. Therefore, incorporating kiwis into one’s diet can provide healthful benefits over time despite potential short-term disruptions in blood sugar regulation.

(7) Vitamin Deficiencies

Kiwi is a nutrient-rich fruit containing vitamins A, C, E, and folate. However, consuming too much of it can lead to vitamin deficiencies in some individuals. Vitamin C deficiency may result in fatigue and easy bruising while consuming excessive amounts of kiwi can also cause Vitamin E deficiency which presents with neurological issues such as muscle weakness or impaired vision.

Furthermore, insufficient intake of both vitamin D and A can occur due to overconsumption of the fruit, manifesting in weakened bones or dry skin/eyes respectively. Additionally, micronutrients found within kiwi such as iron, magnesium, zinc, potassium, and folate are essential for bodily functioning; however, their availability becomes limited if consumed in high quantities. Deficiencies in any of these minerals may present with symptoms including dizziness, brittle nails, or digestive issues.

(8) Increased Risk Of Bleeding

Assessing potential risks associated with consuming kiwi fruits is essential due to their high Vitamin K content, as a deficiency in this vitamin may result in excessive or uncontrolled bleeding. Various risk factors must be taken into consideration when assessing such likelihood, including individual health status (e.g., existing conditions and medications), diet and lifestyle habits, family history, etc.

Blood tests can also provide useful information about levels of clotting factors which can help determine if there is any underlying condition present that could increase hemorrhage risk after eating kiwi fruit. Through these assessments, healthcare professionals can guide so individuals who experience side effects from eating kiwi can manage them effectively without negatively impacting overall health.

(9) Teeth Staining

Kiwi consumption has been linked to dental discoloration due to its acidic content, which can erode tooth enamel. Discoloration caused by kiwi is similar to that of coffee or tea in terms of color and density. Teeth whitening products or professional bleaching services are available for individuals experiencing such problems related to kiwi consumption. Good oral health practices including daily brushing, flossing, and periodic visits to a dentist can help reduce the risk of permanent teeth discoloration.

It is recommended that those who consume significant amounts of kiwi regularly practice good dental care habits. If discoloration persists despite proper maintenance of dental hygiene over time, teeth bleaching may be necessary. Therefore, individuals need to monitor their intake levels when consuming kiwi to avoid potential issues related to stained teeth or enamel erosion.

(10) Increased Risk Of Kidney Stones

Kiwi consumption has been associated with an increased risk of kidney stones in specific individuals. This is due to the citric acid found in kiwi fruit, which can disrupt the balance of minerals necessary for a healthy kidney system by increasing levels of calcium and oxalate. Those with a history of kidney stone formation should monitor their diet and not exceed recommended limits on kiwi intake.

Symptoms associated with kidney stones should be addressed by consulting a doctor before making dietary changes, while regular monitoring and urine tests can help detect early signs of mineral imbalance related to kiwi consumption. Taking prompt measures may help maintain renal health and prevent further complications from developing.


Kiwi is a highly nutritious and tasty fruit with many health benefits. However, it may also cause Oral Allergy Syndrome, allergic reactions, digestive issues, skin irritation, vitamin deficiencies, increased risk of bleeding, teeth staining and an increase in kidney stones forming. Therefore, caution should be exercised when adding this fruit to one’s diet.

Consulting a medical professional can provide appropriate guidance about how to safely enjoy kiwis. Individuals suffering from existing medical conditions or allergies should avoid consuming the fruit. In conclusion, though there are some potential side effects linked with consuming kiwi, its nutritional value makes it a great addition to any balanced diet if consumed in moderation. It is recommended to seek a doctor’s advice before making dietary changes.
