How much Pineapple Juice will Cause a Miscarriage?

Miscarriage is undoubtedly a sensitive and challenging topic that affects many women. Understandably, you might be curious about various theories and remedies surrounding this issue, including the idea that consuming pineapple or pineapple juice could potentially induce or increase the risk of miscarriage. So, let’s get to the bottom of it, shall we? In this article, we’ll dive into the pineapple and miscarriage connection and how much pineapple juice will cause a miscarriage, or can pineapple cause miscarriage(?), separating fact from fiction and exploring what the scientific community says about it. Grab a pineapple slice and join us to unravel the truth behind this controversial claim!

What are the important things that can cause a miscarriage in the first eight weeks?

Miscarriages happen often and are often hard to stop. Early miscarriage is the loss of a pregnancy before 12 weeks. It happens in about 10% of all pregnancies. It must be very upsetting if you’ve had more than one loss soon after getting pregnant for no clear reason. So, what makes losses happen early, between 6 and 8 weeks?

Most of the time, early miscarriages are thought to be caused by chromosome problems that stop the baby from growing. While this may be true in some cases, it is not always true. Different things can cause miscarriages at different times during a pregnancy, and it can be upsetting not to know why.

Before putting an embryo in the womb, doctors suggest preimplantation genetic testing for aneuploidy (PGT-A) to check for chromosomal imbalances (aneuploidy) in the embryos. Even though this method has been very helpful, it is not foolproof because the checked cells do not always show the whole embryo.

The placenta and its precursor, the trophectoderm, have more cells that don’t have the right number of copies, so PGT-A tests those cells. Sometimes, an embryo turns into a normal baby, even though PGS testing says it is aneuploid.

But PGT-A is a common way to find out if an embryo is alive and if it has a chance of staying alive through your pregnancy. We offer IVF with PGT in Mexico, Thailand, Malaysia, India, Cyprus, and Denmark, if you’re considering this.

Problems with the embryo’s chromosomes still cause most early miscarriages in women. What else could cause a pregnancy to end early? 

The less likely cause of miscarriages in early 6-8 weeks:

Hyperactive immune system

Because a baby has genetic material from both the mother and the father, it is always 50% foreign to the body and immune system of the mother. During a normal pregnancy, the immune system changes to accept the baby.

But if your immune system is overactive or you have auto-immune diseases, the baby may be seen as a foreign object and attacked by the body. This leads to problems with embryo implantation, clinical pregnancies, and losses that happen too soon.

Problems with the embryo’s chromosomes and problems with the mother’s immune system are the most common reason for early loss.

Other reasons for miscarriages between 6 and 8 weeks of pregnancy

Other than problems with the chromosomes or the immune system, there are other reasons for early losses, such as:

Anatomical abnormalities of the uterus

If uterine abnormalities are not found, they can cause repeated miscarriages. More than 65% of women with a septate uterus ended up having a miscarriage, according to a study that was published in the Journal of Human Reproduction. 

In the same way, an early loss can be caused by a uterus that is bicornuate, unicornuate, didelphic, T-shaped, or tipped. If you have big fibroids, your doctor may suggest that you take them out so you can have a safe birth.

Not every tumour needs to be taken out. How likely a fibroid is to cause a miscarriage varies on where it is in your uterus.


Infections are the cause of about 15% of all early losses. Bacterial vaginosis, caused by an imbalance of the normal bacteria in the vagina, HIV, Gonorrhoea, and cytomegalovirus (CMV), increases the chance of miscarriage.

Uncontrolled diabetes or high blood pressure

They looked at 1,228 women who had had at least one loss before. During the study, 797 women got pregnant, and 188 of them, or about 24%, lost the baby again.

Even if their blood pressure was normal before they got pregnant, each 10 mm increase in systolic blood pressure increased the risk of miscarriage by 8%, and each 10 mm increase in diastolic blood pressure increased the risk of miscarriage by 18%.

Thyroid disease

Hypothyroidism and high TSH levels make it more likely that a pregnancy will end early. If your TSH level is higher than 4.5 mU/L, you are more likely to have a loss early.

Blood clotting

Your blood is more likely to clot if you have genetic or familial thrombophilia. When blood clots form in the placenta, the chance of a miscarriage or loss of the baby increases. Some doctors tell all IVF patients to get tested for “antiphospholipid syndrome” so that if it is present, it can be treated with medicine to improve the chances of getting pregnant.


Medicines like Misoprostol, Methotrexate, retinoids, and some NSAIDS are bad for pregnancy and may cause a miscarriage to happen early. You should never take any over-the-counter medicine during pregnancy without first talking to your doctor.

Food poisoning

Food poisoning won’t always cause a miscarriage, but it can kill the growing embryo in some situations. Listeria is a bacteria that can cause miscarriage. It can be found in soft, unpasteurized cheeses and other uncooked foods. A miscarriage can also be caused by Salmonella and Toxoplasmosis, found in boiled eggs and raw meat.

Environmental causes

Too much contact with dangerous chemicals like lead, arsenic, mercury, pesticides, etc., can make you more likely to have a miscarriage. Talk to your doctor to find out if your setting could cause miscarriages.

What does pineapple do to a pregnant woman?

Pineapple is a delightful tropical fruit that is beneficial to your health in a variety of ways. However, there are a few factors to keep in mind when eating pineapple while pregnant.

Bromelain is an enzyme that is found in pineapple. Bromelain is thought to have anti-inflammatory and digestive effects. Bromelain, in large amounts, has been said to possibly smooth the cervix and make the uterus contract. Because of this, some people think eating too much pineapple could make you more likely to have a miscarriage or go into labour early.

It’s important to know that the amount of bromelain in a normal dose of pineapple is usually safe for pregnant women. As part of a healthy diet, pineapple probably won’t hurt you if you eat it in small amounts. But there may be risks if you eat a lot of bromelains or take very concentrated pills.

If you are pregnant and have questions regarding your food, it is important to seek personalised advice from a healthcare practitioner. They may provide advice based on your specific circumstances and answer any questions you may have regarding pineapple or other foods.

During pregnancy, it’s usually ideal to consume a nutritious, well-balanced diet containing various fruits and vegetables. If you have any concerns or questions, don’t be frightened to discuss them with your doctor or nurse. They can provide you with valuable guidance and information.

How much pineapple juice will cause a miscarriage?

No clear answer exists regarding how much pineapple juice can cause a miscarriage. 

Studies found that drinking a lot of pineapple juice, especially early on in a pregnancy, may make it more likely to happen a miscarriage. 

Pregnant women shouldn’t drink more than 4 ounces of canned pineapple juice daily. 

Also, talking to your doctor before eating or drinking anything while pregnant is important.

How many raw eggs can cause miscarriage?

It’s reasonable that you might be worried about what you eat while pregnant, but I want to be clear that I’m not qualified to talk about specific amounts of raw eggs and how they might affect a miscarriage. It will be best to talk to a healthcare professional, like an obstetrician or a qualified dietitian, about your food choices. At the same time, you are pregnant to get accurate and personalized advice.

There is a chance that salmonella germs could be in raw eggs, which can make you sick. Eating a contaminated egg might make you feel sick, throw up, or have diarrhoea. In serious cases, it could risk both the mother’s and the baby’s health.

Most people are told not to eat raw or boiled eggs during pregnancy because they could make them sick. Cooking eggs until the yolk and white are both hard is safe and can help reduce the risk of bacteria getting into the eggs.

Regarding food safety during pregnancy, it’s always best to err on the side of caution. If you have any questions or concerns about your diet, including whether or not you should eat eggs, you should talk to your healthcare provider to get advice tailored to your needs.


Is it okay to drink pineapple juice during pregnancy?

Yes, drinking pineapple juice in moderation is usually safe during pregnancy. Bromelain is sometimes found in pineapple juice, but it is generally diluted, and the amounts people normally drink are not likely dangerous.

Can pineapple cause preterm labor?

There isn’t a lot of scientific proof that eating pineapple causes babies to come early. Pineapple has a small amount of bromelain, which is usually not a problem unless it is eaten in large amounts or as a strong supplement.

Should you avoid pineapple completely during pregnancy?

During pregnancy, you don’t have to stay away from pineapple entirely. Pineapple is a healthy and tasty food that can be part of a healthy diet for a pregnant woman. As with any food, you should eat in balance. Enjoy pineapple as part of a healthy diet, and if you have questions or worries, talk to your doctor or nurse.

Are there any other foods you should avoid during pregnancy?

Pineapple is usually safe to eat in small amounts, but there are other foods you should be careful about during pregnancy. Some of these are raw or undercooked eggs, milk that hasn’t been pasteurized, fish high in mercury, and deli meats that might have listeria germs. Talking to your doctor or a trained dietitian about your diet during pregnancy is a good idea if you want full advice.
