Here's a tight, curated reading list - enough to build the modern + Ayurveda picture yourself, without drowning you in options.
1. Subserosal Fibroid (Modern/Allopathic)
Best single source - pathogenesis focus:
Comprehensive Review of Uterine Fibroids: Developmental Origin, Pathogenesis, and Treatment (PMC) - covers MED12 mutations, subserosal vs intramural location correlation, hormonal drivers (estrogen/progesterone), and myometrial stem cell theory.
Textbook backup (if you want a classic gynec-path framing): Sleisenger & Fordtran's GI/Liver Disease and Campbell-Walsh Urology both have concise leiomyoma pathology sections in my library, but for fibroid samprapti-equivalent (etiopathogenesis) the PMC review above is more complete than either.
2. IBS (Modern/Allopathic)
Best single source:
StatPearls - Irritable Bowel Syndrome (NCBI Bookshelf) - free, well organized: gut-brain axis, visceral hypersensitivity, motility, microbiome, epidemiology, diagnostic criteria (Rome IV).
3. Fibroid in Ayurveda (Arbuda/Garbhashaya Granthi)
Primary article for samprapti:
Ayurvedic Intervention in Uterine Fibroids: A Case Series (PMC) - directly states the samprapti: Tridosha vitiating Rakta, Mamsa, and Meda Dhatu admixed with Kapha producing Granthi/Arbuda.
Second reference (broader classical correlation):
Pedagogical Review on Ayurveda Concept of Uterine Fibroid (Garbhashayagata Arbuda)
4. IBS in Ayurveda (Grahani Roga)
Best source - also gives you the modern-Ayurveda bridge directly:
A Comparative Study of Jatharagni Vikriti in Grahani and IBS - lays out the full Samprapti Krama (Nidana Sevan → Dosha Prakopa → Sthana Samshraya in Grahani → Agni Dourbalya → Ama formation → Srotorodha) and maps Ama to modern concepts (undigested proteins, dysbiotic metabolites, LPS).
Second reference:
Ayurvedic Perspective of Irritable Bowel Syndrome (JAIMS) - focuses on Ama accumulation as the core factor.
5. For the relation between the two conditions
There's no direct modern paper linking subserosal fibroid specifically to IBS, but the closest validated model (use this as your reasoning template) is the endometriosis-IBS literature, since both involve pelvic organ cross-sensitization/visceral hypersensitivity:
Endometriosis and Irritable Bowel Syndrome: Systematic Review and Meta-analysis (Frontiers) - shows ~3x IBS risk with pelvic pathology and explains the shared pathophysiological mechanism (visceral-visceral cross-talk, shared autonomic/pelvic nerve pathways).
On the Ayurveda side, the natural bridge is Ama and Agni: vitiated Jatharagni/Ama (Grahani) circulating and lodging in Rakta-Mamsa-Meda can be reasoned as a contributing Nidana for Granthi/Arbuda formation, since both diseases share Kapha-Vata dushti and Agni dourbalya as root factors. Both articles above (#3 and #4) give you the vocabulary to construct this link yourself.
6. Guna-based angle (for your assignment's Ayurveda depth)
None of the above articles isolate guna analysis cleanly, so for that specific lens go to the classical source rather than a review paper: Charak Samhita, Sutrasthana Ch. 1 (Guna-Dravya relationship) and Ashtanga Hridaya Sutrasthana for the standard guna pairs - Guru-Laghu, Sheeta-Ushna, Snigdha-Ruksha, Sthira-Chala, Manda-Teekshna. Apply them like this while writing:
- Granthi/Arbuda: Kapha-Meda dushti brings Guru, Sheeta, Snigdha, Sthira, Manda, Slakshna, Sandra gunas -> explains the fixed, slow-growing, firm, non-tender nodular character of a subserosal fibroid.
- Grahani/Ama: Vata-Kapha-Ama brings Guru, Sheeta, Manda (from Kapha/Ama) alternating with Ruksha, Laghu, Chala (from Vata) -> explains the alternating/erratic bowel pattern typical of IBS.
That guna contrast (static-heavy pathology in the uterus vs erratic-light pathology in the gut, both rooted in a common Kapha-Ama base) is actually a strong angle for your "relation" section.
Work through these on your own - come back if you want help structuring the Nidana-Dosha-Dushya-Srotas-Samprapti Ghatak table or the treatment (Chikitsa) plan for either condition.
