I have severe upper abdominal pain when eating watermelon...the weird thing is..that it doesn't always happen..i'm not sure why...I've decided to just steer clear of them now though...coz it's not worth the 15mins on the floor curled up in a ball...lol..
I get the same issue with watermelon. Never had this problem before, then again I don't recall eating this much watermelon. My symptoms came after only 2lbs of it. Funny though, takes 5-10 minutes for the pain to kick in.
My wife and I are only a week into this and went 100% cold turkey on everything else. When I used to eat watermelon it was completely fine but now when I eat it I get the same issue.
I'll occasionally get pain in my right shoulder if I eat too many grapes at one sitting or sometimes just too cold. I also get tit it sometimes if I make too large a banana smoothie, anything over 1.5 litres at one sitting. But never have a problem with water melon or get abdominal pain.
I did read online that gall bladder problems can cause both abdominal pain on the right hand side just below the ribs & in the right should/arm after eating. But I think a more likelier reason for me at least is just gas or trapped wind from eating too fast.
Finally find people that have the same experience i do after eating watemelon, grapes and other high glycemic fruits. I just had a 10 minute attack after eating 2 cups of watermelon. From the diaphragm up i get intense achey pain that also radiates thru the upper arms. I am also rolling on the floor from it. I suspect it is a result of the sugar because I took a blood sugar reading during the attack and I was at 7.4 mmol/133mg from a starting point of 4.2 mmol/75.6mg. I am not diabetic and use the blood sugar testing and as a way to understand my body's response to food.
About 30 years ago when I drank 250ml of sugar pop, I had a similar attack. Now this only happens from high glycemic fruit - I love watermelon - but looks like I have to stay away from it :)
I also took 600mg of chromium polynicotinate 5 mins into the attack to help end the pain faster. It is now 45 minutes past the attack and my blood sugar is at 5.7 mmol/ 102.6mg.
You already food combine, right? I know if there's any remnants of starchy food or nuts in my tummy I will get stomach pain upon eating watermelon. I try my best to eat it only in the morning, or 2 hours after eating any other fruits or veg.
mine is not stomach, it is above the diaphragm and upper arms. I had an empty stomach, nothing to eat for 14 hours before.
I notice that I belch and burp alot after eating watermelon... must be taking alot of air in while I eat it for some reason.
