Well,this problem according to my experience is related with the uterus
mainly after pregnancy
.If the uterine muscle don't contract well after pregnancy then the apana vikruti takes place;due to this the vayu accumulates and srotorodha becomes prominent. this also affects the blood circulation and mental health.
1)Application of hing surround umbilicus
in paste form at least at bed time
2)prataplankeshwar rasa/nityanada rasa/various guggule kalpa/shankha bhasma/asthimajjapachak yoga
and many more drugs with
3)dhanwanter/kalyanaka/mahapanchagavya/sukumar ghritam thrice a day is quite effective.
4)easy digestive food is recommended.
5) good mental health supports treatment.
6)hot application of brick, hot metal pad on abdomen region at least for 30 mins essential to anuloma the vayu.
These all medication are based on my nadi chikitsa and references from ayurvedic samhitas.You should take an appointment from ayurved vaidya having knowledge of nadi chikitsa. Good luck!
