Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find vertigo very disturbing and often report associated nausea and vomiting. [6]
Each episode of vertigo typically lasts less than one minute. [3] Nausea is commonly associated. [7] BPPV is one of the most common causes of vertigo. [1] [2] [8] BPPV is a type of balance disorder along with labyrinthitis and Ménière's disease. [3] It can result from a head injury or simply occur among those who are older. [3]
Early pregnancy bleeding (also called first trimester bleeding) is vaginal bleeding before 14 weeks of gestational age. [ 1 ] [ 2 ] If the bleeding is significant, hemorrhagic shock may occur. [ 1 ] Concern for shock is increased in those who have loss of consciousness , chest pain, shortness of breath , or shoulder pain.
In the first trimester, a standard ultrasound examination typically includes: [12] Gestational sac size, location, and number; Identification of the embryo and/or yolk sac; Measurement of fetal length (known as the crown-rump length) Fetal number, including number of amnionic sacs and chorionic sacs for multiple gestations; Embryonic/fetal ...
The exact length of each trimester can vary between sources. The first trimester begins with the start of gestational age as described above, that is, the beginning of week 1, or 0 weeks + 0 days of gestational age (GA). It ends at week 12 (11 weeks + 6 days of GA) [4] or end of week 14 (13 weeks + 6 days of GA). [37]
Vertigo is a condition in which a person has the sensation that they are moving, or that objects around them are moving, when they are not. [1] Often it feels like a spinning or swaying movement. [1] [2] It may be associated with nausea, vomiting, perspiration, or difficulties walking. [2] It is typically worse when the head is moved. [2]
[1] AFI is the score (expressed in centimetres ) given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus . To determine the AFI, doctors may use a four-quadrant technique, [ 2 ] when the deepest, unobstructed, vertical length of each pocket of fluid is measured in each quadrant and then added up to the others, [ 3 ...
True cervical pregnancies tend to abort; if, however, the pregnancy is located higher in the canal and the placenta finds support in the uterine cavity, it can go past the first trimester. With the placenta being implanted abnormally, extensive vaginal bleeding can be expected at time of delivery and placental removal.
