9 Potential Side Effects & Health Risks Of Eating Ginger

Ginger is celebrated all over the world for all of its health benefits. From soothing digestive issues to alleviating nausea, this root has been cherished for centuries. However, while it is often hailed for its therapeutic properties, there are circumstances where ginger should be avoided.

Ginger Side Effects & Health Risks

In this article, we’ll dive into the instances where ginger might not be the best fit for your health. Understanding these situations can ensure that you harness the best of ginger’s benefits while safeguarding your well-being.

1. Bleeding Disorders

If you have a bleeding disorder (1), it’s crucial to be cautious about your diet. Ginger is known to have blood-thinning properties, which could exacerbate bleeding in individuals with bleeding disorders. While it’s a popular spice and herbal remedy for various ailments, its potential impact on blood clotting makes it a concern for those already prone to excessive bleeding.

The active compounds in ginger, such as gingerol (2) and salicylate, possess antiplatelet and anticoagulant properties. These components can interfere with the body’s natural clotting process, leading to prolonged bleeding and potentially worsening the condition in those with bleeding disorders.

Individuals with such disorders need to consult their healthcare providers before incorporating ginger into their diet. Healthcare professionals can provide personalized guidance based on an individual’s unique health profile and the severity of their bleeding disorder.

2. Diabetes

Ginger has been observed to potentially lower blood sugar levels. Although this may be beneficial for some, it can pose risks for people who are already managing their blood sugar levels due to diabetes. Sudden drops in blood sugar can lead to dizziness, weakness, and even fainting, making it crucial for diabetics to monitor their ginger intake closely.

Moreover, ginger has natural blood-thinning properties. While this can be beneficial for people with normal blood clotting function, it can be troublesome for diabetics who may already experience issues with blood clotting due to their condition. Excessive ginger consumption could further exacerbate this problem, leading to potential complications.

Furthermore, some diabetics may experience digestive issues when consuming ginger. Ginger, known for its ability to stimulate the digestive system, may cause discomfort, bloating, or even worsen existing digestive problems in these cases. This can lead to further complications in managing diabetes, especially when gastrointestinal disturbances can affect blood sugar levels unpredictably.

3. Gallbladder Issues

When the gallbladder is not functioning optimally, it struggles to efficiently release bile, which is vital for digesting fats. Ginger, being a naturally spicy and pungent herb, can stimulate the production of bile in the gallbladder, potentially causing discomfort and worsening the condition.

Also, since it has strong blood-thinning properties, ginger could pose risks for those with gallbladder problems, as any complications in this delicate organ can lead to bleeding and other serious health issues.

Even though ginger is celebrated for its anti-inflammatory and antioxidant properties, people suffering from gallbladder issues should approach its consumption with caution. They should consult a healthcare professional before incorporating ginger into their diet, as it could potentially aggravate their symptoms and hinder the healing process.

Opting for other soothing and digestive-friendly alternatives such as chamomile or peppermint tea may be a safer choice for individuals looking to manage their gallbladder issues (3) without exacerbating them.

4. Heart Conditions

For those dealing with heart conditions, the use of ginger might pose certain risks. This is primarily due to its potential effects on blood circulation and blood pressure. Ginger has been known to possess properties that can stimulate blood flow and improve circulation, which could lead to an increase in heart rate. For individuals with pre-existing heart conditions, this could potentially worsen the issue and result in adverse cardiovascular effects.

Moreover, ginger has natural blood-thinning properties that can affect the blood’s ability to clot. While this might be advantageous for some people, it could be problematic for those with heart conditions who are already taking blood-thinning medications. The combination of ginger with these medications might further thin the blood, leading to complications such as excessive bleeding or bruising.

5. Medication Interactions

For individuals taking specific medications, especially those used for blood clotting, high blood pressure, and diabetes, it is crucial to be mindful of the potential interactions between these medications and ginger. Ginger’s natural properties, including its ability to thin blood and lower blood pressure, can potentially interfere with the effects of these medications, leading to unpredictable outcomes and adverse health risks.

Additionally, people on certain medications for blood clotting, such as warfarin (4) or aspirin (5), need to be vigilant about their ginger intake. Consuming ginger alongside these medications might intensify the blood-thinning effects, resulting in an increased risk of bleeding. For people on medication to control blood pressure or diabetes, ginger can affect blood pressure and blood sugar levels. This may cause unpredictable changes, potentially undermining the efficacy of the prescribed treatments.

6. Being Underweight

If you are underweight, it is crucial to be mindful of your dietary choices, as certain foods can affect your weight management further. Ginger is often celebrated for its potential to aid digestion, reduce nausea, and alleviate inflammation (6).

Nevertheless, its natural properties can inadvertently contribute to challenges for people striving to gain or maintain a healthy weight. The primary concern arises from ginger’s ability to stimulate the digestive system. It can increase the production of digestive enzymes (7), potentially leading to a faster metabolism. This may result in a decrease in nutrient absorption.

For those trying to maintain a healthy weight, boosting their metabolism can make it harder to consume enough calories. Ginger’s appetite-suppressing potential might worsen this issue.

People struggling with being underweight should consult a healthcare professional or nutritionist for dietary advice. While ginger is beneficial for many, those dealing with underweight concerns should be cautious and explore alternative options for managing their weight effectively.

7. Pregnancy

Some studies suggest that consuming high doses of ginger during pregnancy could potentially increase the risk of miscarriage. Therefore, it’s advisable to stand on the side of caution and moderate ginger intake, especially in the first trimester when the risk of miscarriage is comparatively higher.

Moreover, ginger’s ability to act as a blood thinner might affect the clotting process, which could pose concerns during childbirth or any related procedures. This could potentially lead to increased bleeding, creating challenges during delivery or even postpartum (8).

Despite its many benefits, ginger might also trigger issues like heartburn and discomfort for pregnant women, particularly those who are prone to gastrointestinal distress. Given these potential complications, it’s recommended to consult with a healthcare provider before including ginger in your diet during pregnancy.

In essence, while ginger can be a valuable addition to a healthy diet for non-pregnant women, its consumption during pregnancy should be approached with care and awareness. Prioritizing regular consultations with a healthcare provider and maintaining moderation in consumption can significantly reduce any associated risks. By staying informed and mindful, expecting mothers can make informed decisions about their dietary choices, safeguarding both their well-being and that of their developing child.

8. Low Blood Pressure

The active components in ginger, such as gingerol and zingerone (9), are responsible for its unique properties. These compounds act as vasodilators, widening blood vessels and subsequently causing a drop in blood pressure levels. For those already dealing with low blood pressure issues, the consumption of ginger can intensify these symptoms, making it imperative to exercise caution.

Moreover, ginger can stimulate the production of certain hormones and neurotransmitters. These include serotonin and norepinephrine. This stimulation has the potential to contribute to a further decrease in blood pressure. This physiological response can have adverse effects. Especially for individuals prone to experiencing sudden drops in blood pressure.

9. Surgery

When preparing for a surgical procedure, it is crucial to be mindful of certain foods and supplements that could interfere with the body’s response to anesthesia and other medications administered during the operation. Ginger may heighten the risk of excessive bleeding during surgery, potentially complicating the process and increasing the likelihood of postoperative complications.

Moreover, ginger’s natural ability to affect blood sugar levels (10) could pose a challenge for individuals with diabetes, as it might interfere with their regular insulin intake and cause fluctuations in blood glucose levels during the surgical procedure. Maintaining stable blood sugar levels is important for a successful surgery and a smooth recovery process.

Healthcare providers typically advise patients to refrain from consuming ginger considering the potential impacts of ginger on blood clotting and blood sugar regulation. This includes ginger in the form of supplements, teas, or as a culinary ingredient. It is recommended to do this at least one week before any scheduled surgical intervention. This precautionary measure aims to mitigate any potential risks. This is done to ensure the optimal safety and well-being of the patient throughout the entire surgical process.


To sum things up, ginger is a versatile and healthy spice with many benefits. However, it’s essential to be aware of situations where it’s best to avoid ginger. If any of the issues mentioned apply to you, it’s important to seek advice from a medical expert before adding ginger to your meals. Keeping a watchful eye when needed ensures you can relish the benefits of ginger without any concerns.
