Patient discussion about experiment

Q. Has anyone have any experience with this? I’m 15 years old male and having acid reflux. I have tried lot of meds but nothing is effective and I did not get any remedy. I came across something which says Chinese herbalists can help or even cure it. Has anyone have any experience with this? If you think it is a good idea? Please answer and I will be really grateful!

A. hey, waylon. if you want to try chinese medicine, go for it, as long as you understand clearly how does that medication treat you.
in acid reflux condition, some notes you need to remember are:
- you need to eat regularly
- you need to reduce your stress
- avoid some foods like: acid foods, coffee, spicy foods

and maybe you can try -if you want- consume daily yogurt with apple cider vinegar. apple cider vinegar is believed to be able to help gastric problem.

Q. Can anyone here share with me your experiences….? hey, hi to all…..Very recently I came to know about amniocentesis. With this we can see the baby`s gender..Can anyone here share with me your experiences….?

A. No my dear amniocentesis is not used to find baby`s gender rather its ultrasound for it. Amniocentesis is used to detect any genetic problems such as Down’s syndrome or any other chromosomal abnormalities but not gender of the child. Even infection of the amniotic fluid is checked during amniocentesis. They are also used to check the maturity of the baby`s lungs. Yes it is done under the guidance of an ultrasound. If anyone wants to check for gender they have to go for an ultrasound.

Q. Could anyone share your experience here? your attention here please…..One of my friend is pregnant and after a long and multiple diagnosis she has been confirmed positive for breast cancer. She is badly depressed and is much worried about the child and the effect it will have during pre/post birth. She wants the child to be healthy and normal. Could anyone share your experience here?

A. A) It shows the love and affection the mother has towards the expectant baby. It is good that her breast cancer is diagnosed because it is difficult when one is pregnant. Breast cancer will not harm baby at all, what harms the baby are some of the treatments for breast cancer - and these depend on how advanced the cancer may be. If at early stage her lump will be removed or have surgery for the affected area. The chemotherapy treatment or the medications will be carried after your 1st trimester. This will reduce the harm a baby can get. On advanced stages of cancer, due to radiation treatment and chemotherapy involved with surgery makes the situation tough and makes the survival difficult for mother and baby or even both. So it depends on the stage of your cancer, which you must ask the treating doctor. In early stage of cancer the survival of both mother and baby is possible.Better check her cancer stage. I wish her speedy recovery and safe delivery.
