Screening & Identification of High-Risk Pregnancy + Garbhopaghatakara Bhava & Garbha Vikruti
PART I: SCREENING & IDENTIFICATION OF HIGH-RISK PREGNANCY
Definition
A high-risk pregnancy is one in which the pregnant woman, fetus, or neonate is at significantly greater than normal risk of morbidity or mortality before, during, or after delivery compared to the general obstetric population. Screening is the systematic identification of these pregnancies so that appropriate levels of care, monitoring, and intervention can be provided.
Objectives of Screening
- Identify women at increased risk of complications early (ideally at first ANC contact)
- Ensure appropriate referral to specialist or tertiary care
- Prevent maternal and perinatal mortality and morbidity
- Plan delivery at the right facility and level of care
Screening Methods
1. History Taking (Anamnesis)
Thorough history is the cornerstone of risk stratification. Key areas:
| Domain | Details |
|---|
| Age | <20 years (young primigravida) or >35 years (elderly gravida) |
| Parity | Grand multipara (4 or more), primigravida at extremes of age |
| Past obstetric history | Stillbirth, preterm birth, PPH, neonatal death, previous LSCS, recurrent abortion |
| Medical history | Hypertension, diabetes, cardiac disease, renal disease, thyroid disorders, epilepsy, TB, HIV |
| Family history | DM, hypertension, hereditary disorders |
| Socioeconomic/nutritional | Low BMI (<18.5), MUAC <23 cm, illiteracy, poverty, poor ANC attendance |
2. Physical Examination
- Height (short stature <145 cm - contracted pelvis risk)
- Weight and BMI (obesity BMI >30 or underweight BMI <18.5)
- Blood pressure (hypertension >140/90 mmHg)
- Pallor (severe anaemia, Hb <7 g/dL)
- Uterine size, fundal height, lie, presentation (malpresentation after 36 weeks)
- Oedema assessment
3. Investigations / Laboratory Screening
| Test | Purpose |
|---|
| Haemoglobin | Anaemia (Hb <7 g/dL = severe) |
| Blood group & Rh typing | Rh-negative status - risk of isoimmunisation |
| Blood pressure | PIH, preeclampsia |
| Random blood glucose / OGTT | Gestational diabetes mellitus (GDM) |
| VDRL/RPR | Syphilis |
| HIV test | PMTCT planning |
| Urine (albumin, glucose, microscopy) | Preeclampsia, UTI, GDM |
| Thyroid function (TSH) | Hypothyroidism |
| Ultrasound | Fetal anomaly, growth restriction (IUGR), placenta previa, multiple pregnancy |
4. First Trimester Screening (Combined Test)
- Maternal age + nuchal translucency (NT) on USG at 11-13+6 weeks + serum markers (PAPP-A and free beta-hCG)
- Detects risk for chromosomal anomalies (Down syndrome, trisomy 18, 13)
- A high-risk combined screening result (e.g., 1:150) prompts chorionic villus sampling (CVS) or amniocentesis
5. Second Trimester (Anomaly Scan)
- Detailed anatomical survey at 18-20 weeks
- Detects structural anomalies, cardiac defects, neural tube defects
WHO ANC Components for Risk Identification
According to WHO (2016 ANC Guidelines), every ANC contact must include:
- Detection of anaemia, hypertension, diabetes, and gestational infections
- Ultrasound (at least once before 24 weeks)
- HIV and TB screening
- Tobacco, substance use enquiry
- Intimate partner violence enquiry
- Birth preparedness counselling
Criteria for Identifying High-Risk Pregnancy (PMSMA/India Guidelines)
The following conditions must NOT be missed at ANC and should be prominently marked on the mother-child protection card:
| Category | Conditions |
|---|
| Haematological | Severe anaemia (Hb <7 g/dL) |
| Hypertensive disorders | PIH, preeclampsia, eclampsia |
| Infective | Syphilis (+ve), HIV (+ve), active TB |
| Metabolic | Gestational diabetes mellitus, hypothyroidism |
| Age-related | Young primi (<20 years), elderly gravida (>35 years) |
| Obstetric | Twin/multiple pregnancy, malpresentation, low-lying placenta/placenta previa, previous LSCS, bad obstetric history (BOH) |
| Fetal | IUGR, polyhydramnios, oligohydramnios |
| Other | Cardiac disease, renal disease, epilepsy, previous uterine surgery |
Pregnancy as a "Stress Test"
Pregnancy is increasingly recognized as a physiological stress test that can unmask subclinical vascular or metabolic disease in women who appear healthy. Complications such as preeclampsia, gestational hypertension, and gestational diabetes are not merely pregnancy problems - they identify women at significantly elevated risk for CVD, hypertension, and metabolic disease later in life. Women with preeclampsia have ~2-fold higher risk of future hypertension and CVD; those with early-onset preeclampsia have up to 8-fold higher risk. This makes antenatal screening a critical long-term preventive health opportunity. (Creasy & Resnik's Maternal-Fetal Medicine)
PART II: GARBHOPAGHATAKARA BHAVA AND GARBHA VIKRUTI
(Ayurvedic Concepts - from Garbhini Paricharya)
A. GARBHOPAGHATAKARA BHAVA
Definition:
The word "Garbhopaghatakara Bhava" is derived from Garbha (fetus) + Upaghatakara (harmful/destructive) + Bhava (factor/element). These are specific factors described in Ayurvedic classics that, when practiced or encountered during pregnancy, are capable of harming, injuring, or destroying the Garbha (fetus) or adversely affecting its development. They are enumerated under Garbhini Paricharya (antenatal regimen) as contraindications.
Classification of Garbhopaghatakara Bhavas:
These are broadly classified into three categories:
| Category | Sanskrit Term | Description |
|---|
| 1. Dietary | Aaharaja Bhava | Harmful foods and drinks |
| 2. Activities/Lifestyle | Viharaja Bhava | Harmful physical activities and conduct |
| 3. Psychological | Manasika Bhava | Harmful mental/emotional states |
1. Aaharaja (Dietary) Bhavas - Harmful Foods
According to Charaka Samhita (Sharira Sthana 4/18), Sushruta Samhita (Sharira Sthana 10/3), and Vagbhata:
- Excessive Ushna (hot) and Tikshna (pungent/sharp) substances - associated with Garbha Srava (abortion), Garbha Shushka (fetal emaciation), Akala Prasava (preterm delivery), and Garbha Marana (fetal death)
- Madya (intoxicating substances / alcohol) - causes fetal abnormalities
- Excessive Mamsa (meat) consumption
- Dried, stale, putrefied, and wet food
- Excessive heavy-to-digest substances (Guru Ahara)
- Foods capable of vitiating Vata: cause deformities, neurological abnormalities
- Foods vitiating Pitta: cause skin disorders, bleeding tendencies
- Foods vitiating Kapha: cause Kustha (leprosy-like skin disorders), Kilasa (skin lesions), Switra (leucoderma), Pandu (anaemia), congenital tooth eruption
- Douhridavamana - disrespecting or denying the desires/cravings of the pregnant woman (Douhridini) - strongly associated with fetal congenital anomalies
2. Viharaja (Activity/Lifestyle) Bhavas - Harmful Activities
- Darana Cheshta - activities far beyond one's capacity, excessive exertion
- Sitting or sleeping on very soft and high places (fall risk)
- Excessive margas - traveling on rough roads, horseback riding
- Holding or suppressing natural urges (Vegadharana)
- Sleeping during the day and being awake at night (disturbing circadian rhythms)
- Exposure to frightening or inauspicious sights
- Visiting cremation grounds, desolate places, dangerous locations
- Wearing Raktavarna Vastra (red garments) - to avoid malefic influences
- Company of women whose children have died
- Drinking rainwater excessively
3. Manasika (Psychological) Bhavas - Harmful Mental States
- Shoka (grief, sadness)
- Bhaya (fear, anxiety)
- Krodha (anger)
- Chinta (excessive worry)
- Negative emotions, stress, and psychological disturbances - these impair uterine blood flow through increased abdominal pressure and catecholamine surges, resulting in abortion or IUFD
Consequences of Garbhopaghatakara Bhavas
When these bhavas are followed, Acharyas describe the following outcomes:
| Complication | Description |
|---|
| Garbha Srava | Abortion/spontaneous miscarriage |
| Garbha Shushka | Fetal emaciation/IUGR |
| Akala Prasava | Preterm delivery |
| Garbha Marana | Intrauterine fetal death (IUFD) |
| Garbha Vikruti | Congenital fetal anomalies |
| Vatabhipanna Garbha (Garbha Shosha) | Fetal wasting due to Vata aggravation and nutritional deprivation |
Prevention of Garbha Vikruti through Garbhopaghatakara Bhava Avoidance
Acharyas emphasize that by avoiding Garbhopaghatakara Bhavas and properly following Garbhini Paricharya, Garbha Vikruti can be largely prevented. The preventive protocol includes:
- Ritumati Paricharya - preconceptional measures
- Garbhini Paricharya - antenatal regimen during pregnancy
- Sutika Paricharya - postnatal care
B. GARBHA VIKRUTI
Definition:
Garbha Vikruti refers to congenital anomalies, malformations, or pathological conditions of the fetus arising in intrauterine life. The word means "abnormality/deformity (Vikruti) of the fetus (Garbha)." It is described as one of the most stressful outcomes of pregnancy since it results in the birth of a deformed but alive infant, or intrauterine loss.
Causative Factors (Nidana)
According to Ayurvedic classics, Garbha Vikruti arises from:
| Cause | Meaning | Modern Correlation |
|---|
| Beeja Dushti | Defect in sperm (Shukra) or ovum (Artava/Beeja) | Chromosomal/genetic mutations |
| Beejabhaga Vikruti | Defect in specific part of the reproductive seed | Gene-specific mutations |
| Atmakarma | Deeds of previous life (karma) | Non-modifiable constitutional factors |
| Kala Dosha | Abnormality of Ritukala (timing of conception) | Epigenetic/developmental timing errors |
| Ashaya Dushti | Uterine deformity or abnormality | Uterine malformations |
| Matur Aahara Vihara Dushti | Mother's faulty diet and lifestyle | Teratogenic exposures, nutritional deficiencies |
| Douhridavamana | Denial of pregnant woman's cravings | Emotional/nutritional deprivation |
| Tridosha Vitiation | Aggravation of Vata, Pitta, or Kapha | Metabolic/vascular disturbances |
Classification of Garbha Vikruti
1. According to Origin (Acharya Sushruta and Vagbhata):
| Type | Sanskrit Term | Meaning |
|---|
| Aadibala Pravrutta (Sahaja) | Inherited from origin | Congenital / genetic (from Beeja) |
| - Matruja | From mother | X-linked maternal inheritance |
| - Pitruja | From father | Autosomal/Y-linked paternal inheritance |
| Janmabala Pravrutta | Acquired after birth/at birth | Phenotypic/epigenetic abnormalities |
| - Rasakrita | Due to faulty nourishment (Rasa Dhatu) | Nutritional deficiency disorders |
| - Douhridavamana | Due to denial of cravings | Psychosomatic/maternal deprivation |
(Aadibala Pravrutta = Genotype abnormalities; Janmabala Pravrutta = Phenotypic abnormalities)
2. Specific Types of Fetal Malformations Described in Ayurveda:
| Condition | Description | Modern Equivalent |
|---|
| Nagaudara | Serpent-like abdomen | Gastroschisis/omphalocele |
| Upvishtaka | Contracted, sitting-position fetal deformity | Fetal akinesia deformation sequence |
| Lina Garbha | Concealed/hidden fetus | Vanishing twin / blighted ovum |
| Napumska | Inability to perform sexual function | Ambiguous genitalia / intersex conditions |
| Vamana | Short stature | Dwarfism (achondroplasia) |
| Vikritaksha | Deformed/disshaped eye | Ocular congenital anomalies |
| Anaksha | Absent eye | Anophthalmia |
| Mooda (Jada) | Mental retardation | Intellectual disability |
| Garbha Shosha / Vatabhipanna Garbha | Fetal wasting due to Vata | IUGR / Fetal Growth Restriction |
| Garbha Vriddhi | Abnormal fetal overgrowth | Macrosomia |
3. Effect of Specific Dosha Vitiation on Fetus:
| Dosha | Dietary Cause | Resulting Fetal Condition |
|---|
| Vata | Vata-aggravating foods | Deformities, crippled limbs, neurological defects, Garbha Shosha |
| Pitta | Pitta-aggravating foods | Skin disorders, bleeding, jaundice-type conditions |
| Kapha | Kapha-aggravating foods | Kustha, Kilasa, Switra, Pandu, congenital tooth eruption |
| Tridosha | All three vitiated | Multiple combined anomalies |
Shad Garbhakara Bhavas and Garbha Vikruti
Ayurveda identifies six factors (Shad Garbhakara Bhavas) that determine normal fetal development. Any abnormality in these leads to Garbha Vikruti:
- Matruja - Maternal factors (blood, soft tissues)
- Pitruja - Paternal factors (bones, nails, hair)
- Atmaja - Soul/karma factors
- Sattvaja - Psychological/mental constitution
- Satmyaja - Factors of compatibility (hereditary adaptations)
- Rasaja - Nutritional factors from mother's diet
Prevention and Management
- Avoid all Garbhopaghatakara Bhavas throughout pregnancy
- Follow complete Garbhini Paricharya (monthly dietary and lifestyle regimen)
- Perform Shodhana (purification) before conception if needed
- Practice Atulyagotriya Abhyasa (avoid consanguineous marriages) to prevent hereditary anomalies
- Marry at appropriate age to optimize reproductive health
- Ensure adequate Rasayana therapy (shatavari, phalaghrita) during pregnancy to nourish all Dhatus
- Use Garbhapala Rasa or Phalaghrita for fetal nourishment
