The bloating is to be expected, especially with the constipation, which is caused by the anesthetic. I suggest some Smooth Move herbal tea to get your bowels moving. Be sure to drink plenty of water. Coconut oil is a very good lubricant laxative as well. Take 3 tablespoons at night, and by morning, it should have worked. Psyllium actually constipates me, for some reason.
For the gas, drink this tea. The cloves dispel gas, the cinnamon is Antibiotic and the fennel also dispels gas. In a sauce pan for every 8 ozs. of water, add 10 whole cloves, 1 stick of cinnamon and a tsp. of fennel seed. Boil for 10 minutes, and let steep for 10 minutes. Add honey and lemon to taste. Make and drink at least 2 cups, and your gas worries will be gone!
