Brief Answer:
You can use stool softeners

Detailed Answer:
Hi! Welcome to health care magic! Thanks for sharing your concerns with us. We will try to help you in best way possible. First of all, it is sad to know what you had gone through.

Based on the history you have shared, it is quite possible that the constipation might be due to the fosernol as it is a recognised side effect but it needs to be continued keeping in view the indication to lower down phosphate levels and the levels should be repeated alongwith calcium and parathyroid levels every three months.

Meanwhile you can use food rich in fibres and other drugs including ketosteril containing essential amino acids and other renal replacement therapy should be continued after discussing with the doctor.

For constipation stool softeners like oral lactulose can be used and glycerine suppositories may be used. One issue with Enemas used in constipation are that these contain high levels of phosphate so these will work in opposite to the primary drug yiu have mentioned so lactulose enemas can be used instead in severe constipation. Motility agents like domperidone can also facilitate gut movement and can be given and also work well with vomiting and nausea. Usually nausea and vomitings are directly caused by increased urea creatinine levels in blood so need to have regular follow up with a nephrologist should be ensured.

Wishing you a speedy recovery. If you have any more questions, feel free to ask. Regards.
