Eating or drinking too much too close to a run can cause a stitch. So, try to avoid large meals for two to three hours before running. Have something light. Also, before running, avoid foods high in sugar or fat as well as fruit, fruit juice, chocolate and dairy products. But its not all down to what you eat and drink.
Stitches also affect people who have consumed little or nothing at all.
A weak abdomen may also be a cause of stitch so you might try exercises to strengthen that area. Also, doing a decent warm-up, especially in cold weather, may help reduce the risk of getting a stitch. There s a variety of suggestions. Some experts suggest that you should stop running, stand upright and stretch by leaning gently sideways towards the opposite side from the painful area. Others suggest bending over from the waist several times. and tiughtening the abdominal muscles.
