The Prevention and Treatment of Recurrent Spontaneous Miscarriage
Miscarriage is becoming a common condition for pregnant women, especially in recent years where miscarriage rates have progressively increased as women try to conceive later in life and more and more patients seek IVF treatment. Traditional Chinese Medicine (TCM) has demonstrated that it can prevent and treat recurrent spontaneous miscarriage (RSM) effectively and successfully. In this article, the author analyses the aetiology and pathology of RSM and discuss the differentiation and general modifications according to her clinical experience. The author will also introduce the modern Western medicine approach regarding the diagnosis and treatment of RSM, particularly in with immunological reactions, and report two case studies.
RSM is a term used when three or more consecutive miscarriages have occurred. It is also known as Habitual Abortion. Miscarriage affects around 25% of all pregnancies . Recurrent miscarriage occurs in at least 15% of confirmed pregnancies during the first trimester (12 weeks) . 21% of IVF pregnancies are miscarried spontaneously , and women around the age of 40 experience nearly 50% pregnancy loss with IVF alone . In Western medicine, there are three stages to a miscarriage or spontaneous miscarriage: threatened miscarriage, incomplete miscarriage and complete miscarriage. There is little to prevent or treat recurrent miscarriage in western medicine. On the contrary, TCM has been treating it for thousands of years, not only preventing miscarriage but also maintaining the pregnancy until full term, and therefore increase the live birth rate.
TCM Aetiology and Pathology
According to TCM philosophy, therefore we focus on determining the underlying causes of RSM. There are six main factors according to my clinical experience and the TCM literature that I have researched.
1. Deficiency of kidney and spleen, disharmony of chong and ren channels
The kidney is considered as ‘the origin of congenital constitution’, it stores essence, dominates growth, development and reproduction. The spleen is ‘the material basis of the acquired constitution’, and ‘the source of qi and blood’. The chong channel is the sea of blood, and the ren channel is the sea of yin channels, arising from the uterus in women and is related to conception. Both of them are responsible for blood supply to the foetus. A kidney and spleen deficiency will lead to an inadequate quantity of essence and blood and a disharmony of the chong and ren channels. As a consequence, the foetus cannot be nourished and miscarriage occurs.
2. Deficiency of kidney qi with blood stagnation in the uterus
Women born with a constitutional kidney qi deficiency; or those who have taken the oral contraceptive pill long term; or have had more than one consecutive miscarriage; or many failed IVF attempts, or several strong hormonal drugs have been used can impair the kidney qi, causing kidney qi deficiency and inadequate essence, blood stagnation in the uterus, where the foetus is devoid of blood supply and stops growing, eventually miscarrying.
3. Deficiency of qi and blood:
The spleen and stomach transport and transform the food we eat into usable nutrients and energies, and are considered as “the source of qi and blood”. A spleen or stomach deficiency could cause inadequate blood production and the sinking of qi, consequently failing to nourish and hold the foetus, leading to a miscarriage.
4. Yin deficiency with blood heat
A woman born with a constitutional yin deficiency, or long term emotional factors such as stress, worry, anxiety, fear, anger or grief, can cause liver qi stagnation, which eventually turns into liver fire and blood heat ; or suffers from heat syndromes such as infection during pregnancy. The heat will attack the foetus in the uterus and cause a miscarriage.
5. Damp heat stagnating in the uterus
Severe endometriosis or fibroids that have been inflamed or urinary tract infections (UTI) during pregnancy can produce excessive heat and damp in the body, stagnating in the uterus. This can affect the development of a foetus. It may eventually lead to a miscarriage if left untreated.
6. External factors-Traumatic injury
Any falls, accidents, impacts, or physical work may impair the chong and ren channels, causing disharmony of qi and blood. As a consequence, foetus growth and development may be affected and threaten a miscarriage.
Differentiation and Treatment
Traditionally there are four patterns of miscarriage. However, I have modified them according to my clinical experience and divided them into six patterns.
1. Kidney yang and spleen qi deficiency
It is commonly seen in women with Luteal Phase Defect (LPD), which can cause infertility initially and miscarriage in the early stage if a pregnancy is achieved.
Signs and symptoms
Pain in the lower back; sinking sensation in the lower abdomen; vaginal bleeding during early pregnancy; dizziness; frequent urination and feeling cold; pale tongue and a weak pulse.

Western Medicine Approach on Diagnosis and Treatment
Recent research has been suggested that in some cases of human reproductive failure (RSM and infertility), they may be the consequence of immunological abnormalities . Approximately 80% of miscarriages are caused by an immunologic reaction . Dr. George Ndukwe has developed the reproductive immunology programme at CARE for RSM in collaboration with the immunology laboratory at the Chicago Medical School in the USA. There are five categories of immunologic problems that can cause pregnancy loss .
• Autoimmune disorders - lack of the blocking antibody to pregnancy:
In couples that are a close genetic match, there is a lack of the Blocking antibody to pregnancy. The embryo or foetus is rejected and the pregnancy fails. The treatment for this is Lymphocyte immune therapy (LIT).
• Development of antibodies to Phospholipids
Antiphospholipid antibodies can cause placental thrombosis (thrombophilias), starving the embryo or foetus, resulting in a miscarriage. This is called Antiphospholipid Syndrome (APS) or Blood clotting disorder. The use of low doses of Aspirin and Heparin in the cycle and through pregnancy has been shown to improve pregnancy outcome .
• Development of anti-sperm antibodies and anti-nuclear antibodies
Women can develop anti-sperm antibodies which kill the sperm as it enters the vagina, or kills the developing embryo preventing implantation. Anti-nuclear antibodies can directly attack the embryo or foetus and cause it to abort. The treatment for this is steroids such as Prednisolone or Dexamethasone, started on day six of the menstrual cycle and continued until at least 13 weeks of pregnancy.
• Elevated Natural Killer (NK) cells and elevated Cell Designation (CD) cells and Altered Th-1/Th-2 ratios
All these factors can attack the fertilized eggs and prevent implantation, resulted in a miscarriage. Possible treatment for this may include LIT, Intravenous Immunoglobulins (IVIg), Humira, low dose Aspirin or Prozac.
• Hypothyroidism and hyperthyroidism
Approximately 23-35% of women with RSM have anti-thyroid antibodies , which may be indicative of these thyroid disorders. The medication for this is Thyroxine. However, this research is still in the experimental stages and the therapeutic effect has not been clearly established. These drugs can be very expensive, and there are potentially serious adverse reactions.
Other possible causes of RSM
• 70% of defected conceptions are caused by Chromosomal abnormalities and genetic diseases .
• Premature ovarian failure (POF): high follicle stimulating hormone (FSH).
• Luteal phase defect (LPD): inadequate progesterone production.
• Uterine abnormalities.
• Uterine adhesion or cervical lesion.
• Endometriosis or fibroids.
• Incompetent cervix.
• Rubella, toxoplasmosis, appendicitis, pneumonia, or urinary tract infection (UTI).
Case one: Kidney yang and spleen qi deficiency, together with traumatic injury.
Jane, 31 years old, solicitor. She had achieved five pregnancies, one resulting in a live birth, one miscarried at 12 weeks, and another three miscarried at 5-6 weeks. She conceived again five months later after the last miscarriage, and went to see the consultant in the Early Pregnancy Assessment Unit (EPAU) at the hospital. She was told that they could neither conduct any investigation during pregnancy, nor offer preventative treatment. Instead, they advised her to try alternative medicine. She was five weeks pregnant and felt tired and cold, extremely stressed and anxious, experienced lower abdominal pain and backache, frequent urination, pale complexion. She also had a pale tongue with patched coating, and a deep, thin pulse.
Acupuncture points: Baihui (DU 20), Yintang (EX-HN3), Neiguan (PC 6), Shenmen (HT 7), Zusanli (ST 36). Moxa on Guanyuan (Ren 4), Qihai (Ren 6), Shenshu (UB 23) and Mingmen (DU 4). This was done weekly until 14 weeks, and then once every 4 weeks until 29 weeks.
Herbal prescription: Huang Qi, Dang Shen, Chao Bai Zhu, Dang Gui, Bai Shao Yao, Sang Ji Sheng, Xu Duan, Du Zhong, Tu Si Zi, Shu Di Huang, Ai Ye, Sha Ren and Zhi Gan Cao. Six bags a week until 8 weeks, then four bags a week until 12 weeks. Meanwhile, she was advised to work part time.
She had no complains at all after two weeks of treatment, apart from feeling a bit tired and nauseas. She had blood tests and ultrasound scans regularly every 2-3 weeks until 17 weeks, and had found that the foetus was developing well all the way through. Unfortunately, she was involved in a car accident at 29 weeks, had suffered from severe pain on her neck, back, shoulder and chest, headache, stomach cramps, anxiety and insomnia. However, an ultrasound scan showed that the baby was fine.
I altered the acupuncture prescription as follows: Baihui (DU 20), Sishencong (EX-HN1), Yintang (EX-HN3), Neiguan (PC 6), Shenmen (HT 7), Zusanli (ST 36), Taichong (LIV 3), Tanzhong (Ren 17), Jingbailao (EX-HN15), Jianzhongshu (SI 15), Tianzong (SI 11) and a few Ashi points.
The herbal prescription was: Dang Shen, Huang Qi, Bai Shao Yao, Gan Cao, Suan Zao Ren, Shu Di Huang, Tu Si Zi, Xu Duan, Sang Ji Sheng, and Du Zhong. One bag a day for 10 days. She went on to deliver a healthy baby boy naturally at full term.
Case two: Yin deficiency with blood heat
Natalie, 33 years old, company manager. She had been trying to conceive for four years, had achieved five pregnancies, including one natural pregnancy and four IUI pregnancies. Unfortunately, she miscarried one at 9 weeks, and the other four at 4-5 weeks. She had blood tests for immunological reactions and chromosomal defects, the results were normal. She was referred to me when she was undergoing IVF treatment from CARE Fertility hospital.
She always had painful and clotty periods ever since she was young and had to take painkillers for pain relief. She also went on the contraceptive pill for five years before trying for a family. She was physically healthy, but mentally very stressed and busy with her business. She also went to the gym 3-4 times weekly, the excessive exercise leading to profuse sweating. She drank 5-6 cups of tea and coffee each day. She had a red tongue with a thin coating, thread and rapid pulse.
Before egg collection, acupuncture was given to tonify qi and nourish blood, improve egg quality, and prepare her body while she was on the IVF drugs. The points used: Yintang (EX-HN3), Neiguan (PC 6), Hegu (LI 4), Tianshu (ST 25), Guanyun (Ren 4), Zigong (EX-CA1), Xiehai (SP 10), Sanyinjiao (SP 6), Taixi (KI 3), Taichong (LIV 3), Shenshu (UB 23), Geshu (UB 17). Meanwhile, I advised her to stop drinking tea and coffee, to exercise in moderation, and work fewer hours.
After the embryos had been transferred, acupuncture points were altered to support implantation: Baihui (DU 20), Neiguan (PC 6), Shenmen (HT 7), Zusanli (ST 36), Taixi (KI 3). Auricular points: Naodian (Brain), Neifenmi (Endocrine). She was prescribed Clexane injection and Progesterone pessaries at the hospital. I advised her to stop exercising completely for 12 weeks and take it easy.
When she successfully conceived, treatment was changed to maintain the pregnancy: she had a bit of brownish spotting at 6 weeks for one day, but with no abdominal pain or backache. She received an ultrasound scan the next day and the foetus’ heartbeat was detected. I modified the acupuncture points again accordingly during pregnancy. She was fine until 17 weeks when she experienced light bleeding, which was found to be caused by a polyp in her uterus. We monitored her closely, the polyp stopped growing and she had no more bleeding. She eventually gave birth to a healthy baby daughter at full term.
Spontaneous miscarriage can be very heart-breaking, especially after a woman has suffered from fertility difficulties in the past, and gone through years of treatment to achieve the pregnancy. The most overwhelming loss a woman can experience is the reoccurrence of consecutive miscarriages. In some countries, they would not be investigated until it happened at least three times. All they could do is ‘wait and see’. Whenever they managed to conceive, they would go through an emotional roller coaster and wait with tremendous stress and anxiety, which would worsen their condition even further and increase the risk of miscarriage. Therefore when we treat these patients, it is crucial that we strengthen the kidney and tonify the blood to encourage their body to be more conceptive and maintain the pregnancy to full term. Soothing liver qi and nourishing heart blood to ease their mind must also be considered.
When a pregnant woman experiences lower abdominal pain or vaginal bleeding during the early stages of pregnancy, they should be checked to ensure that it is not an ectopic pregnancy. To be able to treat the patients effectively, we must understand their TCM diagnosis and differentiation. The most important rule to remember in treating miscarriage is not to move the qi too forcefully or quicken the blood. Any Chinese herbs or acupuncture points with those functions should be used carefully or completely avoided. For those women who have had previous miscarriages, receiving TCM treatment to prepare their body before conception is just as important as the treatment during pregnancy.
It is necessary to sometimes combine Chinese medicine with Western medicine to achieve the best possible result. However, when we treat pregnant women who have conceived through IVF, ICSI or IUI, I would suggest that we must be extra cautious about prescribing Chinese herbs, especially if they have immunological disorders (which are often prescribed the aforementioned medication). In these cases, I strongly recommend using acupuncture only, unless the patient insists on taking herbs.
