Remission/Improvement/Recovery Your CFS could potentially be a symptom of something else.
I was diagnosed with CFS in late 2025. I have had symptoms since early 2024, going from doctor to doctor hoping any of them could explain what is happening and why, but only one was familiar with CFS and I ended up with this diagnosis.
Finally after all these years, I am finally recovering. At one point my fatigue was so overpowering, even walking all the way to the back of a supermarket left me exhausted.
Ultimately I discovered my CFS symptoms were due to hydrogen sulfide bacterial overgrowth in my gut. One of its symptoms is fatigue. I also had joint pain, insomnia, digestive issues. These are also attributed to CFS, but can also be caused by bacterial overgrowth. The issue is, many doctors are completely clueless and ignorant about dysbiosis and bacterial overgrowths in the gut and the debilitating symptoms they can cause. Many simply label it as "IBS". It's very easy to develop dysbiosis or overgrowth. A course of antibiotics, poor motility, diet can also cause or contribute to it.
Even with the CFS diagnosis, I was never satisfied that this is it. There must be a cause for this CFS. I knew my symptoms started with digestive issues, so the root cause must be there and after having a GI map, it showed overgrowth of hydrogen sulfide bacteria and I could finally start to address it directly.
If you have a CFS diagnosis consider ruling out any overgrowth or SIBO as the potential cause of your symptoms.
