Connecting lactic acid bacteria and probiotics to your symptoms

Strains and dosages differ even if the name 'lactic acid bacteria' is the same

Probiotics are live microorganisms, and the symptoms they are studied for vary by strain and combination. It is difficult to expect the same effect just because they worked for someone else. Keep track of the exact name, strain, dosage, and storage method of the lactic acid bacteria you take.

Decide what improvement you expect and monitor the response

Abdominal pain, bloating,constipation· During diarrhea, set goals one by one and compare your condition before and after taking it. If gas and abdominal pain worsen, do not simply endure it and continue taking it for a long time. If your immunity is significantly weakened or you are undergoing treatment for a severe illness, consult your attending medical team before starting on your own.

Decide whether to continue intake based on your set goals and duration

Decide whether you want to improve abdominal pain, bloating, or stool consistency, and record the exact strain, dosage, storage method, and start date. If there is no change after a certain period or if gas and pain worsen, do not continue indefinitely under the assumption that you are 'adjusting to the gut.' If your immunity is significantly compromised, consult your attending medical team before starting.

If constipation and bloating remain despite taking lactic acid bacteria, can I consider Korean herbal medicine treatment?

This is possible after reviewing your reaction to the current strain, use of laxatives, and records of your diet and bowel movements.
