Bayer Thai Co., Ltd. and Medical Service Department under Bangkok Metropolitan Administration (BMA) held a signing ceremony for a Memorandum of Understanding (MOU) on June 16, 2025, to enhance awareness of endometriosis and improve access to medications and medical services for citizens. This MOU builds on the cooperation established in 2024 and reinforces the campaign's success in encouraging public screening and treatment of chocolate cysts to improve citizens' quality of life.

Mrs. Lertlak Leelaruengsang, Director of the Bangkok Medical Service Department, said that currently, endometriosis, or chocolate cysts, is one of the health issues that women can prevent and treat through proper understanding and access to quality medical services. The BMA has successfully campaigned to educate the public in collaboration with Bayer Thai Co., Ltd. and four hospitals under BMA: Taksin Hospital, Charoenkrung Pracharak Hospital, Ratchaphiphat Hospital, and Sirindhorn Hospital. This has been achieved through various media channels, such as brochures, videos, and activities to promote understanding of chocolate cysts throughout the past year.

Mrs. Lertlak added that “the feedback from this project has led to increased public understanding that the symptoms they are experiencing may indicate the presence of chocolate cysts, resulting in more consultations with specialists and increasing access to medications and medical services, clearly improving the quality of life. Therefore, the signing of this new MOU will enhance our capacity to expand opportunities to other BMA hospitals, ensuring sustainable care, prevention, and treatment of chocolate cysts in the future.”

Furthermore, collaboration with Bayer Thai will support the vision and policies to create a Healthy City as part of the BMA’s 20-Year Development Plan (2018-2038).

Mr. Bradley Williams, Managing Director and Country Division Head of the Pharmaceuticals Division of Bayer Thai Co., Ltd., stated that the collaboration with the BMA reflects our commitment to continuously benefiting society. Under this agreement, the BMA and Bayer Thai will conduct awareness-raising activities regarding endometriosis, educating the public in collaboration with specialized doctors at hospitals and public health service centers under the BMA, as well as disseminating publications and various beneficial activities to help women understand the importance of self-health care and consult with specialists for timely diagnosis and treatment.

Mr. Bradley  said that “Bayer Thai is pleased to be part of enhancing the quality of life for Thai people and creating benefits for the community through various social activities, aligning with the company’s mission to promote ‘Health for all, Hunger for none’.”

Endometriosis is caused by menstrual flow reversing into the abdominal cavity, where these menstrual cells can attach to various organs, potentially growing into adhesions and accumulating in the ovaries, forming dark, chocolate-like cysts, often referred to as ‘chocolate cysts.’ Warning signs include severe menstrual pain, pain during intercourse, pelvic pain when not menstruating, and infertility. Timely diagnosis is crucial. Current treatment options include 1. Medication, 2. Surgery, and 3. Combined treatment of medication and surgery. However, there is no prevention method for this disease. Therefore, if any suspicious symptoms arise, individuals should promptly consult a gynecologist for diagnosis and treatment. For patients who have undergone surgery, there is still a chance of recurrence, so doctors will plan treatment to help prevent long-term recurrence of the disease.
