Garlic is one of the most common ingredients in kitchens worldwide. In addition to its distinct flavour, garlic offers numerous benefits. This is due to its allicin content, a bioactive compound with antimicrobial, antioxidant, and anti-inflammatory properties.

Despite its advantages, excessive consumption or improper use of garlic can cause side effects. This article highlights the potential side effects of garlic to help you make informed dietary choices.

What are the side effects of garlic?

Some possible garlic side effects are as follows:

  1. Digestive issues

Excessive consumption of raw garlic can irritate your digestive system as it is high in fructans. Side effects may include diarrhoea, bloating, and nausea. The potent compounds in garlic, such as allicin, might be difficult for some people to digest, especially when eaten on an empty stomach.

If you have fructans intolerance, limit or avoid garlic to reduce the risk of gas, bloating, and stomach pain.

  1. Allergic reactions

Some individuals may be allergic to garlic, and consuming it can trigger symptoms such as skin rashes, itching, or even difficulty breathing. Severe reactions to garlic include breathing difficulty or anaphylaxis, although such cases are rare.

These reactions can occur due to sensitivity to garlic’s sulfur-containing compounds. If you suspect an allergy to garlic, it is best to avoid it and seek medical advice.

  1. Increase the risk of bleeding

Garlic has blood-thinning properties, which can increase the risk of bleeding in some individuals. Excessive consumption of garlic can be harmful for those on anticoagulant medication like warfarin.

Individuals preparing for surgery or on blood-thinning drugs should consult their doctor before taking large amounts of garlic.

Conclusion

Garlic can help boost immunity, lower blood pressure, and improve heart health. However, it is crucial to consume it in moderation to avoid potential side effects. If you experience any adverse reactions, adjust your intake and seek medical advice. Understanding how different foods affect your body is key to maintaining overall well-being.

Always exercise caution when necessary and prioritise regular checkups. A comprehensive medical insurance policy can cover treatment costs, providing peace of mind and protecting your health.
