Which lifestyle factors actually affect miscarriage risk?
A short list of lifestyle factors has real evidence behind it. ASRM’s 2026 guidance names these:
- Smoking: stopping tobacco and limiting exposure to secondhand smoke are recommended.
- Caffeine: more than about 99 mg a day, roughly one 8-ounce cup of brewed coffee, is associated with increased risk.
- Alcohol: more than three drinks a week is linked to increased miscarriage risk.
- Weight: obesity is an independent risk factor for miscarriage.
- Exercise: low to moderate exercise is not associated with miscarriage. The evidence on high-intensity exercise is less clear.
This list is shorter than the one most women find online, and that is a good thing. It means you can put your energy where it counts instead of trying to control everything.
Small, steady changes are enough. Swapping a second coffee for decaf or tea, or planning alcohol-free weeks, moves you toward these targets without turning daily life into a test you can fail.
Does blood sugar matter for pregnancy loss?
Yes, especially when blood sugar is poorly controlled. ASRM’s 2026 guidance recommends treating uncontrolled diabetes before another pregnancy and checking HbA1c in women with risk factors, such as a higher body weight, a family history of diabetes, age over 40, PCOS, or past gestational diabetes.
HbA1c reflects average blood sugar over about three months, so it gives a steadier picture than a single fasting glucose.
For women with PCOS and insulin resistance, ASRM says metformin may be reasonable, while noting that the evidence is indirect and more studies are needed. That is a conversation to have with your doctor rather than a decision to make alone.
Day to day, blood sugar steadiness is also something you can influence. Building meals around protein, fiber, and healthy fats, and pairing carbohydrates with them, helps avoid sharp spikes. These habits support your overall health whether or not blood sugar played a part in your losses.
If you have never had an HbA1c and any of the risk factors apply to you, it is a simple, reasonable test to ask about.
Does emotional support really change outcomes?
Emotional support matters to how you feel, and there are signs it may matter to outcomes too. ASRM’s 2026 guidance calls psychological support an essential part of miscarriage care, and it reports that women with recurrent loss have about five times the rate of depression.
ASRM also cites an older study of supportive care in the next pregnancy. Women with recurrent loss who received weekly check-ins and ultrasounds had a live birth rate of 85 percent, compared with 36 percent in routine care. The study was small and not randomized, so it cannot prove that support caused the difference. It is still striking enough that ASRM highlights it.
ASRM recommends that health professionals validate a woman’s experience, screen for mood concerns, and offer referral to mental health care. You can ask for any of those directly.
Support also includes your partner, who may be grieving differently. ASRM notes that partners experience depression and anxiety after loss too, often with less support.
What isn't worth spending money on?
Several treatments marketed after recurrent loss are not supported by current evidence. ASRM’s 2026 guidance advises against:
- Blood thinners such as aspirin or heparin for unexplained recurrent loss, because randomized trials found no benefit. They remain appropriate for confirmed antiphospholipid syndrome.
- Routine immune testing and treatment, including natural killer cell testing.
- Inherited thrombophilia panels and thyroid antibody screening.
- Embryo testing during IVF for everyone with recurrent loss, which has not been shown to improve live birth rates compared with trying again naturally, except possibly for women over 40 with a proven chromosomal loss.
Supplements deserve the same scrutiny. Many are sold with confident claims about preventing miscarriage that go well beyond the evidence. Before buying, ask what problem the supplement is meant to solve, whether that problem has been found in you, and what the research actually shows.
Saying no to these is not giving up. It is choosing to spend your money and hope on things with a real chance of helping.
How long should I wait before trying again?
For most women, the right time to try again depends more on emotional readiness than on a calendar. A 2016 study by Schliep and colleagues in Obstetrics & Gynecology found that couples who tried to conceive within three months of an early pregnancy loss were as likely, or more likely, to have a live birth than couples who waited longer.
The researchers concluded there was no physiological reason to delay for couples who feel ready, while recognizing that many people need time to heal emotionally first.
Practical points to consider:
- Ask your doctor whether any part of your evaluation, such as a uterine procedure or blood test, should happen before you try again.
- If a thyroid or blood sugar problem was found, getting it under control first matters.
- Notice whether you feel ready, not just whether you feel pressured by time.
Age adds real urgency for some women, and that is valid. Even then, a few weeks to complete an evaluation and steady yourself is rarely wasted time.
From Heather
What I worked on, and what I want you to know about it.
Between my losses and the IVF round at 44 that worked, I focused on what I could actually influence. For me, that meant reducing toxins in my home and routine, starting acupuncture, and doing real emotional healing work. A nurse once told me, “This is a marathon, not a sprint,” and I repeat it to my clients often.
I won’t tell you those steps are why my IVF round worked. I don’t know that, and my outcome doesn’t predict yours. I share them because they were within my reach, and many of the factors in this article may be within yours.
That is the heart of The Egg Awakening. It sits alongside your medical evaluation, never in place of it. In Fertility Block Mapping we sort what is worth your energy from what is noise, then build a steady plan around the factors the evidence supports, including the emotional support ASRM itself calls essential.
