Cannabinoid hyperemesis syndrome is real! My 23 year old son has had stomach problems since he's graduated high school , back in 2009 he started getting such severe pain with vomiting that would lead him to the ER... The drs ran all sorts of testings and the only thing they would come up with was gastritis . Every year since then it has gotten worse and worse ! While in high school he played football all four years, weighing over 200 lbs of just about pure muscle at 6 feet tall. The last couple years have been bad bouts of pain and usually starts in the a.m. And he has learned that taking hot showers helps and most times keeps him out of the ER. Back I'm aug 2013 he had another episode that brought him to the ER since the multiple hot showers weren't seeming to work! Since this has been an on going thing the drs started asking if he took drugs , he always said no ( and never told them he smoked pot since that was the only drug he did) ct scans , MRI , ultra sounds labs were always in the normal range. When we had a follow up appt with his GI dr his dr asked if there was anything at home he could do to help with the pain , my son replied with " yes I take hot showers !" The dr then asked if he smoked pot to help relieve the pain , I jumped in to say yes! I felt like I was throwing him under the bus but being his mother and worried about him since this has been going on for years with losing weight and suffering tremendously I was willing to do or say anything to get answers and help ! The dr them told us about cannabinoid hyperemesis syndrome , of course my son didn't believe it and me being a smoker also , I had my doubts but was willing to hear it ! Dr said to quit smoking and if the problems stop then problems solved ! My son didn't stop smoking and several weeks later was back in the ER , they admitted him to the hospital since his blood level was low and severely dehydrated! They did scopes up and down and found his galbladder was not working properly and had to remove it , also he had became malnutrition so they had to start feeding him thru the veined ( TPN with picc line which feeds him directly through the heart) he was in the hospital with non stop pain for two months, only home about 4 different times in those two months but came back the next day with pain ( he smoked everytime he came home) this was back in sept when they put the TPN bag on him and he still has it to this day) my son goes to the ER at least once a month if not once a week and they treat him like a drug addict since I told on him for smoking pot and its now on his record ! It takes high doses of *daludid (spelling) to get him out of pain ! The drs can't find anything else wrong with him so I demanded a second opinion which he now has seen a specialist from cedars siani who did an edoscope with ultrasound attached and again , found nothing except imflammed lymph nodes near liver and bile duct but said this shouldn't be causing the amount of pain and nausea with vomiting that he does , they did biopsies and are now waiting for results ! The scope caused a flare up of pain which caused an overnight stay , and has been suffering for two weeks at home after! On this past fri he was back in ER and stayed in hospital over night to control the pain ( we beg drs , since they treat him like crap and say he needs to stop smoking cuz they find nothing wrong) went home the following day and was back again three days later , the pain used to come on after eating or after a bowel movement and most often in the morning , but since being on TPN and not being able to eat his pain comes after a bowel movement I'm the am or for no readin at all , in the am ! His GI dr had just told us there is no reason to keep seeing my son since he's finding nothing wrong and his primary care dr wants to get him off the TPN and back to eating and to see a psycologist since it must be in his head ! I am outraged at the drs since he's on TPN for not being able to eat or poop without pain and his galbladder was bad they found imflammed lymph nodes do there for something must be wrong ! Our only hope now is for him to stop smoking pot to see if the problem stops and if it don't then we can at least say the drs are wrong and to find the problem ! With all this being said I sure hope it is cannabinoid hyperemesis syndrome since there is a cure , to quit smoking !!! Tomorrow will be day one of no smoking for him and as he has tried before I know it's not going to be pretty , looking into NA meetings for him ... Please wish us luck !
