NOTE: This may NOT work for constipation or diarrhea caused by anything other than over-eating fast food and junk food. Please consult your doctor in cases outside of these.
Once in a while, I will indulge in a greasy burger and fries or some junk food, and because my body is not used to these meals, constipation and (sometimes) diarrhea will be right around the corner. (Sorry if this is TMI.)
Many of you may already know about the following concoction, but I will share my experience with it anyway. When it comes to constipation and diarrhea, drinking lemon juice mixed with warm water works like a charm for me! Though I couldn't find any medical explanation on the internet, there are tons of people who also swear by this natural remedy. If I had to take an educated guess, I would assume that the acidity of the lemon helps with digestion. I really don't know as I am not a doctor, but here is the simple recipe I use:
1 part lemon juice (from a fresh lemon)
1 part warm water
Mix the ingredients and drink once to three times a day. If your constipation does not go away (or decrease) in two days, then please consult your doctor.
This works for me. Hopefully it will work for you!
(Also, increase your water and fiber intake to help further combat constipation.)
