Hello and welcome,
Your description is a very close and almost accurate match of IBS
. As you are well aware of the symptoms let us not discuss that.
The best treatment for IBS is the knowledge of your condition. You need to be aware of the food that can cause the condition, or prove to be a stimulus in your case.
The best options are to avoid food which can be natural laxatives, and increase fiber in your diet.
Meva C is a good drug and I would advice the same to you.
Now answering your questions:
1. Yes, this is most probably IBS, and the treatment for IBS is Meva C, instructed by your physician and the treatment might have to be taken with regular intervals to help keep your symptoms absent or at their minimum. Unfortunately there is no other treatment to completely cure IBS.
2. If you follow your Physicians instructions on treatment regime, you shouldn't have any trouble in the future. Learning that this condition is going to stay is the best way to tackle it, along with a healthy diet which best suits you and your system.
3. Most IBS patients experience a cycle, and this is the same reason you only find temporary relief with medication, and especially once the course has been completed. Discuss in detail with your doctor to understand the requirement of a cycle in your treatment as well, before the recurrence of symptoms.
I wish you the best in health and life.
