Brief Answer: (1)In my opinion Endoscopy wont be required. (2)Candidiasis is usually self controlled. Detailed Answer: Hello Welcome to Health Care Magic. My name is Dr Muhammad Ahmad & i will look into your problem. I have gone through your query and would try to help you in the best possible way....... You touched multiple points in your questions and i will throw light on them one by one... biggest concern you have here is about Candida, now to explain the chances, i will explain nature of this fungus, Candida rarely grows on healthy tissue and in healthy person,,,infact it targets damaged tissues or a person with damages defence against germs like a patient of AIDS or Diabetes.Now your question, will you need a specific med for it? : In my opinion if you maintain good health and hygiene your body will itself fight candida off, and Pylokit has a combination of three medicines which aren t directly anti-fungal but a collective effect of anti-biotics in Pylokit and your improving hygiene and eating habits with better functioning of your stomach and Gut should enable your body to fight Candida off...so in my opinion it is more likely that Candida will go away as your defences get stronger. Is there any less invasive test for H-pylori: Yes indeed there are many quite accurate tests for H-Pylori. (1) Serology(blood tests) (2) Urea Breath test using C13 and C14-Urea (3) Faecal Antigen test . In the end i just want to mention that endoscopic biopsy is indeed the Gold standard to finding out diagnosis or cure of H-Pylori but its hard for the patent to bear so it can be discussed with your physician to use alternate tests which may be less accurate but can be good enough to avoid endoscopy. Application of these tests are limited in different cases and that has to be discussed with your physician, with which option he wants to go in your particular case. ... Hope I have answered your query. If you have any further questions I will be happy to help . Wishing you good health !!
