Pregnancy Symptoms

Understanding Pregnancy Symptoms

Pregnancy symptoms are the changes you notice in your body and mood as a pregnancy begins and progresses. They differ from person to person and from one pregnancy to the next. Pregnancy is a medical state that needs regular prenatal care, and any new symptom is best discussed with your obstetric provider.^[1]

Common symptoms

Early signs include a missed period, nausea with or without vomiting, tender breasts and tiredness. Nausea and vomiting usually begin around the fourth to sixth week and ease by the middle of pregnancy.^{[2, 3]} Later in pregnancy, many people notice back or pelvic pain, heartburn, swelling, poor sleep and frequent urination.^{[4, 5]}

Mood changes are also common, and depression and anxiety can occur during pregnancy.^[6]

Causes and risk factors

Most symptoms reflect normal changes: shifting hormones, a growing uterus, extra blood volume and a changing posture. The cause of nausea and vomiting is unknown, but the rise in the pregnancy hormone hCG may play a part.^[2]

More than two thirds of pregnant women have low back pain, and almost one fifth have pelvic pain, usually increasing as the pregnancy advances.^[4] Heartburn can occur in any trimester.^[5]

How it is diagnosed and treated conventionally

Pregnancy is confirmed by testing and tracked through scheduled prenatal visits.^[1] Mild symptoms are usually managed with diet and lifestyle changes. Exercise is encouraged for most uncomplicated pregnancies and can ease some common discomforts.^[7]

When nausea and vomiting are more troublesome, a review of 78 studies found that ginger, vitamin B6, antihistamines and some prescription antinausea medicines improved symptoms compared with placebo, although the overall quality of the evidence was low.^[8] Severe, persistent vomiting with weight loss and dehydration is called hyperemesis gravidarum and often needs hospital treatment.^[3]

Why Pregnancy Symptoms calls for a whole-person approach

Pregnancy symptoms rarely have one cause. Hormones, mechanical load, digestion, sleep and mood all interact, and a symptom such as nausea or back pain can affect eating, rest and emotional health in turn.

For that reason, care for pregnancy symptoms usually combines several small measures under the direction of your obstetric provider. Any complementary care we offer is chosen to fit around that plan.

Hormonal change

The rise in hCG is one proposed contributor to early nausea and vomiting, though the cause is not established.^[2]

Physical load and posture

Back and pelvic pain typically increase as pregnancy advances and can interfere with work, daily activities and sleep.^[4] Regular exercise may reduce pregnancy-related low back pain, although the evidence is of low quality.^[4]

Digestion

Heartburn is among the most common digestive complaints in pregnancy. It can be frequent and distressing, though serious complications are rare.^[5]

Mood and stress

Many pregnant women prefer non-drug options for depression and anxiety and use complementary therapies for them. Studies of these therapies are few and mostly at high or unclear risk of bias.^[6]

Acupuncture as supportive care in Pregnancy Symptoms

What the research shows

The research is limited, and it varies by symptom. For nausea and vomiting, a 2024 meta-analysis of 24 trials with 2,390 women found that acupuncture added to usual medical care reduced symptom scores more than usual care alone. It also found acupuncture comparable to medicine on some measures. The certainty of the evidence ranged from moderate to very low, and the authors called for larger studies.^[9] A 2023 analysis of 33 trials rated the evidence for acupuncture and acupressure as low quality.^[10] A review of acupressure trials found some benefit over sham acupressure, but concluded that strong supportive data are not yet available.^[11]

For back and pelvic pain, a Cochrane review found moderate-quality evidence from single studies that acupuncture improved pelvic pain more than usual prenatal care.^[4] A network meta-analysis of eight trials found acupuncture and sham acupuncture eased pregnancy-related low back pain about equally, and both did better than standard care.^[12]

For heartburn there are too few data to judge acupuncture.^[5] One trial in a review of depression and anxiety in pregnancy found acupuncture reduced the number of women diagnosed with depression, but the evidence overall was weak.^[6]

How acupuncture may work

For pregnancy symptoms, we found no study in this search that establishes how acupuncture works. In nausea trials, the points most often used were on the inner forearm (Neiguan, PC6), the leg and the upper abdomen.^[9] Any benefit may include non-specific effects, since sham acupuncture helped in some back pain comparisons.^[12]

What treatment involves

Treatment uses fine, sterile, single-use needles, usually left in place for about 20 to 40 minutes, with a short course of visits and reassessment. Pregnancy is a reason for extra care, and we ask that your obstetric provider knows you are receiving complementary care. Some people use acupressure on the same points instead of needles.

In prospective studies, about 9 in 100 patients had a minor reaction such as soreness or bleeding at a needle site, and serious events occurred in about 1 in 10,000 patients. These studies were not specific to pregnancy.^[13] The nausea review found no significant difference in severe adverse events between acupuncture and medicine or sham acupuncture.^[9]

Tell the practitioner first if you are pregnant or may be, have a bleeding disorder, take blood thinners, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine as supportive care in Pregnancy Symptoms

The Ayurvedic view

Ayurveda describes pregnancy as a time when digestion, rest and routine need extra attention, and has a classical set of practices for the care of a pregnant woman (garbhini paricharya). These are traditional teachings, not biomedical findings.

Therapies that may be used

During pregnancy, supportive Ayurvedic care is limited to gentle measures:

• Regular, warm, easily digested meals and steady sleep and wake times
• Breathing practices (pranayama) and rest, as described in a clinical overview of Ayurveda in obstetrics^[14]

Panchakarma is not appropriate in pregnancy. Herbal formulas and oil therapies should be used only if your obstetric provider agrees.

What the research shows

We found no clinical trials of Ayurvedic treatment for pregnancy symptoms. One published overview describes Ayurvedic approaches for common pregnancy complaints, but it is a descriptive article, not a study showing benefit.^[14]

Quality is a particular concern. A reported case described a pregnant woman with severe vomiting and anemia whose investigations pointed to lead toxicity, most likely from an Ayurvedic powder she had been taking.^[15]

Herbal medicine as supportive care in Pregnancy Symptoms

Herbs and formulas that have been studied

Ginger is the herb with the most research in pregnancy, mainly for nausea and vomiting.^{[8, 16]} Chinese herbal formulas and other herbs are also used traditionally, but most have not been tested for pregnancy symptoms.

What the research shows

For ginger and nausea, a meta-analysis of 12 randomized trials with 1,278 women found it improved nausea compared with placebo. It did not significantly reduce vomiting episodes, and the authors noted a limited number of trials and low-quality evidence.^[16] A larger review of 78 studies also listed ginger among treatments that helped mild symptoms compared with placebo.^[8] Another meta-analysis rated the ginger evidence as low to moderate quality.^[10]

Safety and herb-drug interactions

Herbs are active substances, and "natural" does not mean safe in pregnancy. A review of medicinal plants warned that some can be toxic to the fetus, stimulate the uterus or act as abortifacients, and that safety can differ by trimester.^[17] For this reason, herbs in pregnancy should be used only with your obstetric provider's agreement, and only if individually prescribed by a qualified practitioner.

Herbs can also interact with prescribed medicines. Reported examples include bleeding with warfarin and changes in blood levels of several drugs.^[18] One study found that about one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[19]

Tell us about every medicine and supplement you take, including prenatal vitamins.

Translating traditional medicine into modern biological language

This is interpretation, not equivalence. Chinese medicine often describes pregnancy nausea as a disorder of stomach qi rising upward, which fits loosely with the focus on stomach and digestive points in nausea trials.^[9] Ayurveda's attention to digestion and routine loosely parallels the lifestyle measures that conventional care also recommends for mild symptoms.^[14]

No study has shown that these traditional concepts correspond to specific biological processes in pregnancy.

How this care fits with your medical care

Pregnancy needs care from an obstetrician or midwife. Our care is complementary: keep all prenatal visits, and do not stop or change any prescribed medicine, including antinausea drugs and prenatal vitamins, without your provider.

We do not diagnose or manage the pregnancy. Please tell your obstetric provider that you are receiving acupuncture or other complementary care, and bring your due date, your list of medicines and supplements, and any recent test results to your first visit. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care.

When to seek urgent medical care

Some symptoms in pregnancy can signal a serious problem and need same-day medical attention.^{[3, 20]}

• Severe or persistent vomiting, or being unable to keep fluids down
• Heavy vaginal bleeding, or bleeding with severe abdominal pain
• Severe headache, vision changes, or sudden swelling of the face or hands, which can signal preeclampsia
• Painful urination or blood in the urine
• Regular contractions or fluid leaking before 37 weeks
• Reduced fetal movement later in pregnancy

For a medical emergency, call 911 or go to the nearest emergency department.
