increases in the early stages of pregnancy. If the mother is malnourished during mid-pregnancy, the baby will also be deprived of nutrients. Also, it has been reported that pregnant women who are too thin are more likely to have premature births.\nWhen too overweight: In cases of obesity in the early stages of pregnancy, there is said to be a higher risk of neural tube defects such as spina bifida, congenital heart defects, and umbilical hernia in babies. There is a higher risk of gestational diabetes. Maternal obesity and gestational diabetes stimulate excessive fetal growth and increase the risk of giving birth to a macrosomic baby weighing over 4000g.\n<\/p><\/div>\n\n\n\n<div class=\"toc\">\n\t<ul>\n\t\t<li><a href=\"#c1\">Introduction<\/a><\/li>\n\t\t<li><a href=\"#c2\">Too Thin During Pregnancy<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c2-1\">Guidelines for Being Too Thin<\/a><\/li>\n\t\t\t\t<li><a href=\"#c2-2\">Effects of Being Too Thin on the Baby<\/a>\n\t\t\t\t\t<ul>\n\t\t\t\t\t\t<li><a href=\"#c2-2-1\">Early Pregnancy<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c2-2-2\">Mid-Pregnancy<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c2-2-3\">Late Pregnancy<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c2-2-4\">Just Before Birth<\/a><\/li>\n\t\t\t\t\t<\/ul>\n\t\t\t\t<\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c3\">Being Too Overweight During Pregnancy<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c3-1\">Guidelines for Being Too Overweight<\/a><\/li>\n\t\t\t\t<li><a href=\"#c3-2\">Effects of Being Too Overweight on the Baby<\/a>\n\t\t\t\t\t<ul>\n\t\t\t\t\t\t<li><a href=\"#c3-2-1\">Early Pregnancy<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c3-2-2\">Mid-Pregnancy<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c3-2-3\">Late Pregnancy<\/a><\/li>\n\t\t\t\t\t\t<li><a href=\"#c3-2-4\">Just Before Birth<\/a><\/li>\n\t\t\t\t\t<\/ul>\n\t\t\t\t<\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c4\">Weight Management During Pregnancy<\/a>\n\t\t\t<ul>\n\t\t\t\t<li><a href=\"#c4-1\">Revising Diet<\/a><\/li>\n\t\t\t\t<li><a href=\"#c4-2\">Is Dieting Okay?<\/a><\/li>\n\t\t\t<\/ul>\n\t\t<\/li>\n\t\t<li><a href=\"#c5\">Effects of Being Too Thin or Too Overweight During Conception<\/a><\/li>\n\t\t<li><a href=\"#c6\">Testing the Baby&#8217;s Condition with NIPT (Non-Invasive Prenatal Testing)<\/a><\/li>\n\t\t<li><a href=\"#c7\">Conclusion<\/a><\/li>\n\t<\/ul>\n<\/div>\n\n\n<p style=\"width:100%;max-width:300px;margin:0 auto;\"><a href=\"\/nipt\/\" class=\"content-bnr about\"><img decoding=\"async\" src=\"\/nipt\/wp-content\/themes\/hiro_nipt\/img\/banner\/nipt02pc.png\" alt=\"\u30c0\u30a6\u30f3\u75c7\u306f\u751f\u307e\u308c\u308b\u524d\u306b\u308f\u304b\u308a\u307e\u3059\u304b\uff1f\"><\/a> <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c1\"><span class=\"ez-toc-section\" id=\"Introduction\"><\/span>Introduction<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>During pregnancy, some women may experience difficulty eating due to morning sickness, resulting in becoming too thin, while others may overeat due to cravings, leading to becoming overweight.<\/p>\n\n\n\n<p>Does becoming too thin or too overweight during pregnancy have an impact on the baby?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c2\"><span class=\"ez-toc-section\" id=\"Too_Thin_During_Pregnancy\"><\/span>Too Thin During Pregnancy<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-1\"><span class=\"ez-toc-section\" id=\"Guidelines_for_Being_Too_Thin\"><\/span>Guidelines for Being Too Thin<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>According to the &#8220;Dietary Guidelines for Pregnant and Lactating Women Starting Before Pregnancy&#8221; announced by the Ministry of Health, Labour and Welfare, pregnant women with a pre-pregnancy BMI of less than 18.5, indicating underweight, are advised to aim for a weight gain of 12 to 15 kilograms during pregnancy.<\/p>\n\n\n\n<p>Furthermore, pregnant women with a BMI between 18.5 and less than 25.0, indicating normal weight, are advised to aim for a weight gain of 10 to 13 kilograms.<\/p>\n\n\n\n<p>If the weight gain falls significantly below these guidelines, it may be considered as being too thin.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"\/nipt\/wp-content\/uploads\/2022\/08\/to-thin-and-overweight01.jpg\" alt=\"\u598a\u5a66\u306e\u75e9\u305b\u3059\u304e\u306e\u76ee\u5b89\" class=\"wp-image-38392\"\/><\/figure><\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"c2-2\"><span class=\"ez-toc-section\" id=\"Effects_of_Being_Too_Thin_on_the_Baby\"><\/span>Effects of Being Too Thin on the Baby<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-1\"><span class=\"ez-toc-section\" id=\"Early_Pregnancy\"><\/span>Early Pregnancy<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>During the early stages of pregnancy, if the intake of food is insufficient and there is a lack of folic acid intake, the risk of neural tube defects in the fetus increases.<\/p>\n\n\n\n<p>On the other hand, during this period, many pregnant women experience morning sickness, and even though they understand that being too thin is not good, they may have difficulty eating as they would like.

If the mother is malnourished during this period, the baby may not receive sufficient nutrients.<\/p>\n\n\n\n<p>In such cases, the baby may become smaller compared to the gestational age due to low nutrition, leading to a condition called intrauterine growth restriction (IUGR).<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"c2-2-3\"><span class=\"ez-toc-section\" id=\"Late_Pregnancy\"><\/span>Late Pregnancy<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>Pregnant women who are too thin are reported to be more prone to premature birth.

As a result, it becomes difficult to conceive.<\/p>\n\n\n\n<p>On the other hand, it&#8217;s also known that overweight women may have difficulty getting pregnant.

The condition of the baby is influenced not only by environmental factors such as the mother&#8217;s weight, but also by the chromosomes they inherit.<\/p>\n\n\n\n<p>Prenatal testing allows for the examination of chromosomal abnormalities in the baby during pregnancy. While amniocentesis and chorionic villus sampling (CVS) provide definitive results, they carry the risk of miscarriage or stillbirth as they involve sampling amniotic fluid or placental tissue.<\/p>\n\n\n\n<p>On the other hand, <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">NIPT<\/a> is performed using the mother&#8217;s blood, eliminating the risk of miscarriage or stillbirth. Although it&#8217;s considered a screening test rather than a diagnostic one, <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/\">NIPT<\/a> boasts high sensitivity and specificity rates of 99.9%, making it highly accurate.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/\">NIPT<\/a> can be conducted as early as the confirmation of pregnancy through ultrasound, allowing for earlier testing compared to other prenatal diagnostic methods.
