4) weight gain and obesity without eating more than before
Reasons for weight gain would be the reduction/slowing of function...hormones, metabolism, etc. or retaining of water...

According to the symptom compass, this could be a CM regeneration stage or in stress phase showing as swelling as a result of long stress

From previous training examples and the case example from the video...
BS issue, could be stress phase as a result of prolonged stress resulting in under function, coldness, etc. It doesn't fully fit the symptom compass for BS regeneration phase due to the temperature being cold, but the other symptoms could fit for regeneration.
