Background Multimorbidity, a prevailing trend in the primary care population of all ages, is a challenge for health care systems that are largely configured for single disease management. Homeopathy has shown competence in the management of chronic diseases, whether they occur as a single ailment or as a multimorbidity. Case History A 35-year-old female patient presenting with hemorrhoids, low back pain, hypothyroidism, fibroadenosis breasts (bilateral), and fibroid uterus was given homeopathic treatment for 33 months at Nandigama AYUSH Lifestyle Disorders Clinic, Andhra Pradesh. She was prescribed the homeopathic medicines Lachesis mutus and Thyroidinum at different time intervals based on the totality of symptoms. Results Following treatment, a reduction in the size of the uterine fibroid and complete regression of breast lumps in ultrasonography were noted. The modified Naranjo criteria total score was 10 out of 13. Further, significant improvement in symptoms and laboratory parameters, such as triiodothyronine (T3), tetra-iodothyronine (T4), and thyroid-stimulating hormone (TSH), indicated that a well-chosen homeopathic medicine may be beneficial in managing multimorbidity. Conclusion This case study reveals a positive role of homeopathic treatment in multimorbidity. More case studies and well-designed controlled should be used to further investigate homeopathic intervention in multimorbidity.
