Cantaloupe can actually help in the treatment of constipation because it has such a high concentration of water in it. Some people who eat an excessive amount of cantaloupe find that they actually experience problems with diarrhea, gas, and in rare cases vomiting if there is an allergic reaction. This particular fruit however does not cause constipation and can in fact do the exact opposite.
Those who have problems with constipation will want to take the time to think about including more cantaloupe in their daily diet. It is a great source of vitamins, minerals, and nutrients which can help with many things besides just constipation.
