📝 Detailed Answer
I have personally tried many trendy supplements in the past, and I realized that if they don't suit your body, they are essentially wasted. Based on that experience, it is important to understand that probiotics are not 'weight loss drugs' in themselves.
First, let's look at the benefits. Probiotics increase beneficial gut bacteria, aiding bowel movements and helping reduce edema (swelling). For those whose bodies feel heavy due to severely impaired digestive function, probiotics can be a great starting point.
However, there are limitations. Since the gut microbiome varies greatly from person to person, what works for one may cause bloating in another. Furthermore, if your overall metabolism has slowed down, it is practically impossible to see significant weight loss through probiotics alone.
In Traditional Korean Medicine (TKM), this condition is often referred to as 'Spleen Deficiency' (Bi-heo, 脾虛), where the Spleen's function is weakened, hindering the proper absorption and transport of nutrients. For such patients, instead of simply adding bacteria, it is far more efficient to clear 'Phlegm-fluid' (Dam-eum, 痰飮—accumulated metabolic waste) and resolve 'Blood Stasis' (Eo-hyeol, 瘀血—stagnant blood) to open up the metabolic pathways first.
Ultimately, the answer is 'it depends on the individual.' If improving gut health is your primary goal, I recommend them. However, for those who gain weight alongside chronic fatigue, a herbal prescription to replenish Qi (vital energy) may be a higher priority. Let's examine together where the blockages in your body are located.
