There is sense in doing detox diets. More than that, there is health in it. Ridding yourself of chemicals in your body that your body can do better without, is what it is and it also is why you need to be doing it.
If you are having difficulty with irregular or painful bowel movements then you are probably suffering from constipation. This condition can make you feel very bloated, uneasy, and very gassy. But this condition is very easily manageable and it can be treated within the confines of your house. It is not an ailment or something that you should be worrying too much about. There are many different ways to approach this problem and there are many constipation remedies that you can try but the best approach is to look at three different things in your life: your hydration levels, your diet, and how much exercise you are getting.
If you live in a city, have a desk job (and a stressful one at that), drive an hour at least each day, and do not do exercise, then you probably are forcing your liver to do extra work trying to do away with all that excess of toxins.
