I am having real problems and I would welcome any advice including on whether I should see a specialist (and if so what type) or whether I should seek further tests. I seem to currently be suffering from a complete loss of appetite combined with a fairly constant feeling of nausea (especially in the morning). I've not actually been sick however, but have retched quite a few times. I am male in my late 50s, and have generally been in good health. I seem to currently be suffering from a complete loss of appetite combined with a fairly constant feeling of nausea (especially in the morning). I've not actually been sick however, but have retched quite a few times. I am male in my late 50s, and have generally been in good health. While my problems started last October, the current severe symptons (as of 10 March) have been going on for a little over a week. In this time I have had to force myself to have any food at all and have largely been sticking to soup, porridge and drinking water and very weak black tea. It's easier to eat a little in the evenings. This is the second period of severe appetite loss. The previous period lasted around 10 days starting just after XMAS. I don't have any fever, although I did when the inital problems started. I'm not having diarrhea or constipation, although I did have diarrhoea at the start of this second period, but didn't for the first period. I have had blood tests and and a stool samples tested, which I'm told were normal, thus ruling out of number of things including anaemia and liver problems. Amylase was also tested for. I was given co-amoxiclav for this second period of appetite loss (for possible diverticulits and due to the diarrhoea). This has not affected the almost total appetite loss (I have just completed the course). I had hoped the stool sample taken when I had diarrhoea might have given some clue, but I don't know how comprehensive the testing is. In late January I had a barium enema, which showed 'early signs of diverticular disease, but nothing to worry about'. I also had a endoscopy which showed the stomach to be normal. I have had several blood tests (including for amylase). All came back normal. I avoided Gluten in the period after XMAS, just in case that's a factor although I don't think it is. Initial symptons in October were waking up the night feeling dizzy and unwell, typical symptons for a virus / bug and that cleared up fine after a couple days. However for the next 6 weeks or so, my appetite was generally a little poor, my digestive system seemed a bit upset (slightly lose stools, queasy stomach). Also, at roughly weekly intervals I would feel a little unwell for a day or so. I had assumed this was a virus being slow to clear. A week before XMAS my stomach started feeling very queasy (lots of gurgling) and this was followed by very poor appetite for about a week, although I was able to eat modest amounts of food and did not have any significant nausea. This settled down for a few days for which I ate normally. However, one evening I got the same stomach feeling of gurgling and queasiness and the following morning the complete lack of appetite and feelings of nausea arrived. My stomach felt a little uncomfortable at times, but there was no sharp pain. I didn't have any fever, although I did when the inital problems started and I didn't have diarrhea or constipation. I have had blood tests and and a stool sample tested, which I'm told were normal, thus ruling out of number of things including anemia and liver problems. I'm quite worried about this - which probably doesn't help! After about 10 days of no appetite and nausea in January the symptons died away significantly. This did follow taking 2 Zantac tablets a day (although this may be coincidence) and appetite is returned to nearly back to normal (especially in the evening) although I did feel a little unwell once and possibly may have had a slight temperature. However my stomach did not feel properly right (unsettled might be the best discription). I took 3 Motillium tablets as well as the Zantac for this period. I stopped taking these when the endoscopy was normal. Because the intermitent unwell feelings continued and my stomach 'wasn't right', the GP prescribed antibiotics in case of diverticulitis. I had diarrhoea half way through, which was put doen to a side effect of the ciprofloaxin. However, I continued to have loose stools after completing the course, but a further blood test and stool sample were normal. Further info - in case it's relevant: I had a Fundoplication operation in 2011 to cure Acid Reflux. This was successful in curing the problem. I had sharp heartburn once during the current issues. I also had had a general anaesthetic for a minor knee op a few days before the sever appetite loss occured.
