I had an oesophagectomy 18 months ago. During the period from initial diagnosis to chemotherapy to post op I lost around 2 stone. Although I eat reasonably well and have a good mixed diet I just cannot put on any weigh and over the past 6 months or so I have lost a further half a stone and I am now struggling to stay over 10 stone. In all other respects I feel pretty good although like many patients do get tired at times. Any thoughts or suggestions?
