Is seborrheic keratosis caused by sugar?

Seborrheic keratosis is a common benign skin growth with a raised, rough, waxy or stuck-on surface. Its development is not explained by a simple sugar exposure. People may notice growths at different times and connect them with a change in food, weight or blood sugar, but timing alone cannot show causation. A pigmented or irritated lesion should not be assumed to be a seborrheic keratosis without examination.

You do not need to restrict sugar solely to treat an established seborrheic keratosis. Choose balanced eating for general health and follow any separate advice you have received for diabetes or other conditions. For the skin growth, avoid picking, cutting or applying household remedies. A clinician can recommend observation or discuss cryotherapy, curettage and cautery, or electrosurgery when the lesion is irritated, repeatedly caught or unwanted for appearance.

Arrange an examination if a growth is new and unlike nearby marks, changes in shape or colour, bleeds, crusts, becomes painful, or grows quickly. Seek advice if several lesions appear suddenly or if the diagnosis is uncertain; the pattern may need a broader assessment.

Does this growth look like seborrheic keratosis? Is there any reason to assess my blood sugar separately? Should we monitor it, sample it or remove it, and what aftercare would my skin need?
