Will eating onions and garlic cause scar proliferation in patients with scars?

Generally, moderate consumption of onions and garlic by scar patients does not directly cause scar hypertrophy. However, excessive intake or having scars in specific healing stages may indirectly affect scar recovery. If in doubt, it is advisable to consult a healthcare professional in advance. Detailed analysis is as follows:

If the scar has stabilized (e.g., formed more than three months ago, without redness, swelling, or itching), moderate consumption of onions and garlic typically has no adverse effects. The nutrients in onions and garlic can normally participate in bodily metabolism. As long as intake is controlled (such as typical culinary seasoning amounts), they will not directly stimulate abnormal scar tissue proliferation or alter the existing scar condition.

If the scar is in the proliferative phase (e.g., less than three months old, accompanied by redness, swelling, itching, or raised appearance) or if the patient is sensitive to onions and garlic, excessive consumption may indirectly worsen discomfort. Onions and garlic are considered irritating foods; excessive intake may trigger inflammatory responses in the body, potentially intensifying symptoms such as redness, swelling, and itching in proliferating scars. While they do not directly cause scar hypertrophy, they might prolong the proliferative phase and impair scar healing.

During scar recovery, it is recommended to limit the consumption of onions and garlic, avoiding raw intake or large quantities. Additionally, keep the scar area clean and avoid scratching or other irritations. If abnormal scar proliferation or discomfort occurs, seek medical advice promptly to identify the cause and receive targeted care.
