C-section scar thickness can still grow thicker, but the specifics vary from person to person. Some women may experience a further increase in localized scar thickness after a C-section, mainly in women with scarred bodies and those who do not pay attention to skin care on a daily basis, prompting irritation from foreign body friction. In addition to scar thickening, infections such as redness, swelling, pain, bleeding or pus may occur. For non-keloid women and some women who take good care of their skin, the scar may not thicken. For those with abnormally thickened scars, they may be treated with topical injections of corticosteroids such as triamcinolone and acetonide, or medications such as mitomycin C and interferon, as prescribed by the doctor. Some of them can be treated with surgical procedures such as keloid contracture release and flap grafting. During the treatment, breastfeeding needs to be suspended to avoid affecting the growth and development of the baby. Cesarean section patients with scars pay attention to skin care, try to wear loose, pure cotton clothing, avoid foreign body friction stimulation. Patients with abnormally thickened scars should go to the hospital in time for a clear diagnosis by the doctor, and cooperate with the doctor for symptomatic treatment.
