Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Sorry to hear about your health issues. Please bear in mind that benign polyps of colon are a common problem happening in 1 out of 4 people. They are reported mostly after 50 years of age and often picked up on screening for bowel cancer. Recurrence is not common but colonoscopy every 3-5 years to pick them up and remove if necessary are advisable. I note that you say you have put on weight. Now that is something that you could work on without having to spend hugely on treatment. Being overweight and having a family history of bowel cancer, increases the risk of this happening, especially in presence of polyps. In balance, I would like to suggest that you take charge of your health especially diet and exercise to control the weight, with immediate effect. There are many online resources available, that could help you achieve this without much expense. Being aware of what and when you eat and how much time you give to active physical exercise is first step. Brisk walking with deep breathing is a no-cost measure to increase your calorie output over and above calorie intake. There are applications on smart phone that can help you record and change your life style. The greatest motivator in your circumstance could be the fact that you have three other young lives to care for and set out example of healthy living for them, by living it yourself. Once you are financially comfortable and immediate health concerns are settled, you could consider gentle bowel detox/ cleanse whichever is more appropriate at the time and then build up gut health with suitable supplements, prebiotics, probiotics and right diet. Importantly, do contact your doctor for a colonoscopy appointment, given that you are reporting bloody or tarry streaks in your stool. I understand that not having insurance is an impediment, but ways can be agreed with your doctor to work round it. May be you can agree a payment schedule that suits your circumstance. You will come to know of possible solutions only if you ask. Communication is key. Take action for your health. Make intent to prioritize yourself, the rest will follow. Hope I have answered your query. Let me know if I can assist you further.
