Prawns contain magnesium, protein, folic acid, vitamin E, niacin and other nutrients, so the left side of the thyroidectomy patients can eat prawns, can replenish the body’s need for trace elements and nutrients, but do not recommend a large amount of food at one time, so as not to increase the burden on the gastrointestinal tract, causing indigestion.

It should be noted that, if the left thyroid gland is hyperthyroidism or thyroid cancer and other diseases such as thyroidectomy, you need to limit the intake of iodine-containing foods, such as prawns, kelp, nori and so on. Patients after left-sided thyroidectomy should actively cooperate with the doctor’s treatment, regular review.
