Topic Explanation:
The forum topic is about a person who has been practicing irrigation for 4 years after having an operation in March 2015. However, they are experiencing troubles with the irrigation process as the water is not going in as it should, and the output is thicker than normal. They are seeking advice and asking if anyone has had similar experiences or any advice to offer.

Advice and Insights:
- A blockage such as constipation or a parastomal hernia could be reasons why the water might not go into the stoma as it should.
- Using an adaptation to an anal catheter can help clear the blockage and deposit the water on the right side of the hernia.
- Consider using a mild stool softener like Citrucel if the problem is due to the consistency of the stool.
- Consulting a physician or stoma nurse if the problem persists is recommended.
- It might be necessary to irrigate every day as leaving the output in the lower colon for longer periods can cause it to become firmer.
- Discuss the situation with a stoma nurse and surgeon to identify the blockage problem and find a way to get the water past the blockage.
- Using gel on the finger to expand the stoma before introducing the cone for irrigation can be helpful.

Conclusion:
The forum participants provided valuable insights and advice on dealing with irrigation troubles, including potential causes and solutions to overcome blockages and difficulties in the irrigation process.
