For decades, endometriosis has been shrouded in a culture of endurance in India. As per Indian Council of Medical Research (ICMR), endometriosis is affecting approximately four crore women across the country. This chronic condition occurs when tissue similar to the lining of the uterus grows in places it doesn’t belong—like the ovaries, fallopian tubes, or even the bowels.
According to a recent ICMR study, patients in India have faced an agonising wait of six to nine years for a formal diagnosis. However, 2026 marks a pivotal shift. With updated global guidelines from the World Health Organization (WHO) and the American College of Obstetricians and Gynecologists (ACOG), the medical community is finally moving away from medical dismissal toward rapid, non-invasive intervention.
Indian gynaecologists delve into non-invasive saliva-based testing, 7-D framework, presumptive diagnosis and advanced ultrasound mapping, allowing for molecular-level detection and immediate treatment that can facilitate a faster diagnosis and offer an alternative to laparoscopic surgery.
The Saliva Test: A diagnostic paradigm shift
The gold standard for diagnosis has long been laparoscopy—a surgical procedure where a camera is inserted into the abdomen. Because surgery is intimidating and expensive, many women delay it for years.
Dr. Anshumala Shukla Kulkarni, head, minimally invasive gynaecology, gynaecology laparoscopic and robotic surgery at Kokilaben Dhirubhai Ambani Hospital in Mumbai, highlights the 2026 breakthrough: the saliva-based diagnostic test.
How it works
1. miRNA as a messenger: Micro-RNAs (miRNAs) are small molecules that act like ‘on/off switches’ for our genes. In patients with endometriosis, the body’s inflammatory response creates a unique pattern among 190 specific miRNAs.
2. Gene array technology: The test uses a multi-sequence array to scan your saliva for this specific signature. Because these markers appear in the bloodstream and saliva long before a lesion is large enough to be seen on a scan, it catches the disease in its infancy.
The test is a major leap because it identifies the disease at a molecular level rather than waiting for physical growth.
Accuracy
According to studies published in NEJM Evidence, the saliva based Ziwig Endotest¬¬, which is available in India, has shown high accuracy for detecting endometriosis. Results indicate a diagnostic accuracy of approximately 96.6 per cent, with 97.3 per cent sensitivity and 94.1 per cent specificity. This means it is excellent at ruling in the disease for patients who have previously been told their scans are clear.
The early-stage advantage
The most significant hurdle in diagnostic delay is that early-stage endometriosis is often not visible on traditional scans.
1. Beyond imaging: Traditional ultrasounds only see endometriomas or deep nodules. They often miss superficial peritoneal endometriosis—which can be just as painful but is too flat for a standard probe to detect.
2. Avoiding negative surgery: Historically, many women underwent diagnostic laparoscopy only for the surgeon to find nothing because the lesions were too small. As Kulkarni notes, the saliva test allows for a diagnosis without the risk of a negative (unnecessary) surgery.
3. Halting progression: By identifying the disease early, doctors can start empiric therapy (hormonal management) to stop these microscopic cells from growing into the dense, scarring adhesions that cause organ damage and infertility. It allows women to get an answer before the disease causes visible physical scarring.
A crucial distinction: Diagnosis versus cure
While the saliva test is a revolutionary diagnostic tool, Kulkarni provides an essential medical reality check regarding treatment, “Diagnosing endometriosis using a salivary test is good for detecting early cases, but it doesn`t mean these patients are cured by medication alone.”
Hormonal treatments (like GnRH antagonists or progesterone) are not a cure. “They only suppress the lesion and give symptom relief. They manage the pain, but they do not necessarily change the underlying disease status,” she explains.
Redefining ‘normal’ pain: The 7 Ds framework
A major barrier to diagnosis is the cultural myth that period pain is normal. Dr. Uddhavraj Dudhedia, director and head (chief), advanced robotic gynaecology, endometriosis, neuro gynaecology, Indo-Swedish uterine transplant program and uro-gynaecology at Nanavati Max Super Speciality Hospital in Mumbai, emphasises that 2026 protocols now use a structured 7 Ds framework to help patients and physicians identify red flags:
1. Dysmenorrhea: Severe period pain that doesn`t get better with rest or standard over-the-counter painkillers.
2. Dyspareunia: Deep, sharp pain during or after sexual intercourse.
3. Dysuria: Pain or a burning sensation while urinating during your period.
4. Dyschezia: Painful bowel movements or lightning pains in the rectum during menstruation.
5. Dysfunctional bleeding: Heavy, irregular, or unpredictable periods.
6. Deep pelvic pain: A heavy, dragging sensation in the pelvis that persists even when you aren`t on your period.
7. Difficulty conceiving: Infertility after six months of trying (for those over 35) or one year (for those under 35).
The presumptive approach: Treatment without surgery
In a radical departure from the past, the 2026 WHO and ACOG guidelines now support a presumptive clinical diagnosis. As Kulkarni explains, “If a patient’s symptoms and medical history align with the new checklists, the use of medication helps to stop the disease from progressing without the need for immediate surgery.”
1. Empiric therapy: Clinicians can now initiate treatments like GnRH antagonists or progesterones. According to Dr. Kulkarni, while these suppress the lesions and provide symptom relief, they allow the patient to avoid negative laparoscopic surgery.
2. The goal: The focus has shifted from finding the lesion to improving the patient’s quality of life. Dr Dudhedia notes that tools like the EHP-30 (Endometriosis Health Profile) quantify how the disease disrupts work or school, providing the ‘good practice point’ needed to justify immediate therapy.
Why standard ultrasounds often fail
Many women are told everything looks normal after a routine ultrasound, yet they remain in excruciating pain. Dr Dudhedia says, “Standard scans often miss superficial endometriosis or deep nodules hidden behind the uterus.”
The 2026 solution: Endometriosis Mapping (IDEA Protocol)
Instead of a basic scan, patients should request Endometriosis Mapping via Transvaginal Ultrasound (TVUS). “This is a specialised, multi-planar sweep of the pelvic compartments. It is often preferred over MRI because it is dynamic—the doctor can move the probe to see if organs are stuck together (adhesions) in real-time,” he explains.
The cost of delay: Why early detection matters
The six to nine year diagnostic lag in India isn`t just about pain. it’s about long-term health. Kulkarni warns of several hidden costs of waiting:
1. Central sensitisation: Over years of untreated pain, the brain and spinal cord become hypersensitive. Eventually, even a light touch can feel painful because the nervous system is stuck in a high-alert state.
2. Organ damage: Untreated endometriosis can cause the fallopian tubes to block or stuck ovaries, making natural pregnancy or even IVF significantly more difficult.
3. The endo belly: This isn`t just bloating, it’s an inflammatory response. The body sends fluid and immune cells to the abdomen to fight the misplaced tissue, causing a distended stomach that mimics irritable bowel syndrome (IBS). New tools help doctors distinguish between digestive issues and endometriosis.
A patient’s guide to overcoming medical dismissal and navigating endometriosis in 2026
If you suspect you have endometriosis, or if you have been told your pain is normal, Kulkarni’s advice is clear, “Medical gaslighting is real for endometriosis patients. Be your own advocate.” These are the specific questions and terms based on the 2026 ACOG and WHO guidelines to ensure you receive the most advanced care available.
The red flag checklist for your doctor
When describing your symptoms to a general physician or gynaecologist, avoid using general terms like bad cramps. Instead, use these 7 Ds and specific clinical indicators to trigger a faster referral:
1. Non-responsive to NSAIDs: Tell your doctor if standard painkillers (like Ibuprofen or mefenamic acid) do not allow you to function.
2. Adolescent warnings: Parents should look for red flags in teens, such as missing school every month or being unable to use a tampon due to pain. Early intervention in the teenage years can prevent Stage IV disease in adulthood.
3. Quality of life disruption: Mention if you are missing school, work, or social events. The EHP-30 tool is now a standard metric for justifying immediate testing.
4. Cyclical gastrointestinal or urinary symptoms: If you have diarrhoea, constipation, or pain during urination only during your period, this points to endometriosis rather than IBS.
5. Shoulder tip pain: Mention if you feel a sharp pain in your right shoulder during your period; this is a key sign of diaphragmatic endometriosis.
Questions to ask your gynaecologist
To ensure you are being treated under the most current protocols, as outlined by Dr Kulkarni and Dr Dudhedia, ask the following:
1. Regarding the saliva test: Am I a candidate for the new saliva-based diagnostic test to avoid an initial diagnostic laparoscopy?
2. Regarding ultrasound: Can we perform an endometriosis mapping or deep endometriosis protocol rather than a standard pelvic scan?
3. Regarding surgery: If we proceed with surgery, are you excision-ready? Will you remove the lesions during the same procedure if they are found?
4. Regarding presumptive diagnosis: Based on my 7 Ds symptoms and history, can we begin empiric therapy now to stop the disease from progressing?
