I want to share some good news! I have finally healed after 15 months of having frequent long haul COVID symptoms. I had COVID in December 2020; my worst symptom was a horrendous headache that lasted a week or so. Other than that, my symptoms were body aches, upset stomach, diarrhea, fatigue and brain fog. The headache and most of the other symptoms went away after about 10 days. I was blessed that I had only very mild respiratory symptoms. A few weeks after I had recovered from the COVID, I became ill for a few days with what I came to know as long haul Covid. I had these symptoms (mild headache, nausea, digestive tract upset, and fatigue) once or more each month for well over a year.
After more than a year of these frequent long haul illnesses, I read medical studies showing that 70% or more of our immune system is located in our digestive tract. I began working diligently to strengthen my immune system by eating cultured vegetables and drinking probiotic drinks daily. I started very slowly with just small amounts of the probiotic food and drink so that my system could adjust slowly. I did this faithfully each day and within a couple of weeks I saw that my symptoms were milder and I was sick less frequently. After only a couple of months of this diet change, I had no long haul symptoms or illness at all and months later I've had no recurrence. I make my own cultured vegetables and my own water kefir ..... these are both rich in probiotics. I know now how very vital it is to maintain excellent gut health for a strong immune system.
I hope my experience will be helpful to others.
