Q. "What is safe to take during pregnancy to treat a yeast infection? I know about cutting out sugar/carbs but are any over the counter treatments OK? Or other natural remedies? Will the infection hurt the baby at all?"
1. Yeast is a dietary-related problem. All of us have yeast residing in our bodies, but it only becomes a problem when it is out of balance. Sugars and carbs "feed" the yeast and can get out of proportion, so that is why it is important to cut out sugar and sugar substitutes if you are struggling with a yeast overgrowth. Aim to satisfy your sweet tooth all (or mostly) from fruit, yet in as small of a quantity as you can stand. Fruit normally is rich in vitamins, so while fructose can also 'feed' yeast, fruit supplies you and baby with important nutrients, so is a smart choice in small quantities for cravings for sweets. Avoid fruit juices, since they are concentrated doses of sugars without the balancing of the pulp and skin which fill you up, naturally limiting over-consumption.
Yeast also loves dairy, so cut down on dairy while treating the yeast infection. During pregnancy, calcium intake is VERY important for your developing baby's bones and teeth, so when you cut down on dairy products, be extra diligent to increase your calcium intake from other sources such as deep green leafy veggies and nourishing herbs such as red raspberry leaf and nettles. (Those two herbs are pregnancy-safe--and indeed nourish you and baby-- and are excellent sources of calcium.)
Increase your garlic intake. A clove of garlic a day is a great anti-fungal.
2. Make sure you are taking a high-quality prenatal vitamin.
3. Take probiotics. During the time of the active infection, eat non-sweetened yogurt several times daily (homemade yogurt is best if you can)--acidophilus capsules are better. Depending on the brand, you can take a fairly high dose, but no matter whether you take yogurt or capsules, and no matter what dose you take, you need to take probiotics daily. If you go with capsules, take the lowest effective dose. If you feel gassy, bloated or nauseous, that's too much, but, again depending on the brand, 4-6 capsules daily is not too much. If you do feel gassy or bloated, decrease your daily dose by one tablet, though it might be hard to gauge if you also have morning sickness! If you have never taken probiotics before, start with the minimum recommended dose on the bottle and increase by one tablet per day, spread out over the day--until your symptoms are gone, you notice side effects, or until you are taking 10 billion organisms per day. Most women should be helped with a dose somewhere between 2 and 5 billion organisms per day.
4. Avoid dampness around the vagina. Dry thoroughly immediately after bathing. You can add yogurt or white vinegar or both to your bath.
5. Treat your spouse at the same time--yeast can infect men and be passed back to wives through intimate contact. Avoid intercourse during this time of the active yeast infection.
6. Pregnancy itself makes yeast overgrowth more likely, but antibiotic use greatly increases the likelihood of yeast infections, both vaginal and nipple yeast infections, called thrush. Avoid antibiotics during the pregnancy and birth if at all possible; they increase the likelihood of thrush afterwards, especially for women prone to yeast infections. Thrush infections make breastfeeding much more uncomfortable!
7. Other more desperate measures: prepare a douche with an unsweetened live culture yogurt (1 T.) to 1 quart water mixture. (Some advocate undiluted yogurt douches--I guess you will need to experiment with what works for you.) You can also use organic, high-quality cottage cheese soaked into a lady's pad and worn inside your underwear. Change several times per day. Use until you have no symptoms for 12 hours. (High-quality cottage cheese also has live cultures in it.) For vaginal itching relief, you can do the same type of soaked pad with yogurt and diluted white vinegar mixture.
Hope you feel better soon! If symptoms persist, make sure to contact your health care provider. All that itches is not necessarily yeast.
