Patients with gallbladder cancer do not need to eat separately from their family. Although it is necessary for gallbladder cancer patients to avoid spicy and stimulating foods to reduce inflammatory irritation and better control the progression of the disease, this is especially true for symptomatic gallstone patients, who can control the disease progression through diet without special treatment, simply needing regular follow-up with ultrasonography to monitor changes in size. If significant symptoms occur, surgery is needed to achieve a cure, so treatment is relatively complex and focuses on usual dietary habits. Additionally, patients with gallbladder cancer should consume foods that are rich in protein to supplement the energy needed by the body.
