My mother had a laryngectomy and stomach pull up 17 years ago following cancer of the voice box. She got the all clear about 5 years after the surgery. However she recently started to get weak spells and dizzy spells and has been losing a lot of weight. She eats little and often but it seems to me that her digestive system isn't working properly. She eats enough but she is still losing weight. She has been referred to the dietician and has been booked for an xray. It is worrying to see her so thin. She has had 4 episodes of the weakness and dizzy spells in the past two months. Is this common in patients with her condition? It is very worrying.
