Twenty-first week of pregnancy
The little one kicks more frequently and carrying the baby bump around is more and more tiring. With the scientific advice of the gynecologist Elisabetta Canitano, president of the non-profit association Vita di donna, let’s see what happens to the woman’s body and that of the child during the twenty-first week of pregnancy.
Symptoms of the twenty-first week of pregnancy
At this stage of pregnancy the uterus is constantly expanding, resulting in an increase in pressure on the organs and lungs. This can have consequences such as shortness of breath, fatigue and a greater stimulus for the urination (in short, you will pee more often).
Other frequent symptoms can be:
Health advice in the twenty-first week of pregnancy
Watch out for gestosis
From the twentieth week of pregnancy onwards there is a risk – albeit statistically infrequent – that a pregnant woman will contract preeclampsia (or gestosis), a very particular condition which, in addition to episodes of headaches or temporary visual disturbances, can also manifest itself with inconspicuous symptoms such as a blood pressure unbalanced (higher a maximum 140 and a minimum of 90) or the presence of protein in the urine at levels over 290 mg / l.
The causes of this pathology are not yet completely clear but if not adequately treated, its consequences can degenerate into violent convulsions with generalized damage to the organs (eclampsia) with potentially fatal consequences for both the mother and the fetus.
Advice: to sleep more peacefully it is good monitor blood pressure frequently, undergourinalysis and, especially if you fall into one of the categories most exposed to gestosis risk, do some more checks, such as Doppler flowmetry of the uterine arteries
What to do in the twenty-first week of pregnancy
Continue to monitor the power supply
Nutrition must always be healthy and balanced, especially during pregnancy. Lweight gain it is an essential factor in gestation, but this should not be an excuse to indulge in an unregulated diet. According to the recommendations of the American Institute of Medicine, in the second and third trimesters, weight gain should be on average:
- about 500 grams per week for women who play underweight;
- about 420 grams per week for women who started pregnancy with the right weight;
- about 280 grams per week for women who have left overweight
- of about 220 grams per week for obese women.
Beware of food supplements
In general, there is no strict need to take vitamins and minerals, unless there is a specific indication from the doctor. If there are no specific problems, a varied diet, rich in fruit and vegetables, may suffice. In particular, iron supplements should not be introduced unless blood tests show a specific deficiency.
Fluorine and oral health
For what concern fluorine, the ministerial guidelines for the promotion of oral health suggest the possibility of taking it starting from the third month of pregnancy, in the dose of 1 mg per day, but in the same document it is written that the lack of solid scientific data on efficacy does not allow to strongly recommend it. A more recent ministerial document, the Recommendations for the promotion of oral health in perinatal age, finally concludes that, on the basis of the available data, fluoroprophylaxis in pregnancy is not indicated.
The fetus in the twenty-first week of pregnancy
The taste buds they are formed on the tongue: thanks to them, the child will be able to appreciate the taste of food. At 21 weeks, the fetus is also able to swallow. The baby sleeps most of the time, but when he is awake he kicks and somersaults. Its weight is around 300 grams and is around 16-18 centimeters long. At 21 weeks, the fetus is able to swallow.
The eyebrows begin to form around this time.
