一 、岁胸13歲女孩胸圍多大正常
兒童醫院林醫生介紹13歲女孩胸部剛開始發育不久 ,岁胸一般情況下13歲女孩胸圍在70到80厘米之間是岁胸正常的。胸圍太小的岁胸女生也不用太在意 ,隨著年齡的岁胸增大會逐步增長。

二 、岁胸13歲女孩胸圍怎麽測量
1、岁胸先將衣服脫去 ,岁胸較輕鬆地站著(但是要筆直),雙腳並攏 ,臉向正前方,微微抬起下。
2、將皮尺水平地圈在胸圍(突出點)上,由鬆慢慢收緊。量時應用手將乳房輕輕托起 ,就好象穿著胸衣一樣 。
3 、這時可以輕鬆地測得自己的實際胸圍與胸下;而胸線(乳房底部所呈現的線條)也可方便地測得。
4 、胸圍尺寸(通常說的“上胸圍”):以BP點(即乳點bustpoint)為測點,用軟皮尺水平測量胸部最豐滿處一周 ,即為胸圍尺寸 。
5 、下胸圍尺寸 :用軟皮尺水平測量胸底部一周,即為下胸圍尺寸。下胸圍尺寸換算(1英寸=2.54厘米)

三、13歲女孩胸部怎麽護理
在青春期前期的乳房保護十一、二歲的女孩,一般乳房就開始發育。乳頭出現硬結並有輕微的脹疼 ,乳房慢慢豐滿起來,以後就進入青春發育期 。
這個時期要注意的是,女孩應當養成戴乳罩的習慣 。乳罩大小要合適 。乳罩太大了,對乳房起不到支托和保護作用;乳罩太小了 ,會妨礙乳房的發育 。
如果女孩年滿十五歲,乳房還沒有發育 ,就應到醫院去檢查 。在青春期 ,由於人體內雌性激素的影響 ,乳房容易長良性腫瘤。
所以一旦發現乳房裏有腫塊 ,就應及時到醫院檢查,乳房腫塊要“三早”。
