Hoefler Text, a typeface designed in 1991, uses text figures and represents the numeral 1 as similar to a small-caps I. One is most commonly a determiner used with singular countable nouns, as in one day at a time. 1 is the most common leading digit in many sets of real-world numerical data.

The representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. It is the first and smallest positive integer of the infinite sequence of natural numbers. Some women find subsequent pregnancies milder; for many, especially HG, the recurrence is real and worth preparing for. Recurrence for milder NVP also common. Particularly useful for women whose GP / midwife isn't taking severe nausea seriously enough.

Severity vs intensity — not a continuum; some women have HG without especially 'sicker' symptoms but with dehydration risk. Used by obstetric teams worldwide to triage symptoms and track response to treatment. Continue antiemetic plan; usually settles by 28 weeks for most. NOT just bad morning sickness — distinct clinical entity.

• In philosophy, the number 1 is commonly regarded as a symbol of unity, often representing God or the universe in monotheistic traditions.
• An element with a multiplicative inverse is called a unit, generalizing the role of 1.
• The RCOG Green-top Guideline 69 provides clinical guidance on managing this condition.
• Other common numeral prefixes for the number 1 include uni- (e.g., unicycle, universe, unicorn), sol- (e.g., solo dance), derived from Latin, or mono- (e.g., monorail, monogamy, monopoly) derived from Greek.
• Also, period 1 in the periodic table consists of the two elements hydrogen and helium.

Care guidance — surviving pregnancy nausea

Pregnancy Sickness Support UK — charity supporting women with NVP / HG (pregnancysicknesssupport.org.uk). Some women cope with mild-moderate nausea at work with adjustments (snacks at desk, fresh-air breaks, anti-sickness meds). Requires urgent treatment. Affects 70-80% of pregnant women. 20% have ongoing nausea past 20 weeks. Typically 4-12 weeks of pregnancy.

Hyperemesis gravidarum (HG) is a severe form of pregnancy sickness that goes beyond typical morning sickness. The PUQE score (Pregnancy-Unique Quantification of Emesis and Nausea) is a validated pregnancy nausea and vomiting assessment tool. If you are worried about your symptoms, please contact your midwife, GP, or NHS 111. Assesses the severity of nausea and vomiting in pregnancy using 3 symptom questions.

In the religious world, most of today's major religions teach of a single, common God, and the importance of unity among people based on our common humanity. It represents a single entity and is commonly regarded as the fundamental unit of counting and measurement. In philosophy, the number 1 is commonly regarded as a symbol of unity, often representing God or the universe in monotheistic traditions. Digitised data is represented in physical devices, such as computers, as pulses of electricity through switching devices such as transistors or logic gates where "1" represents the value for "on". It can be traced back to the Brahmic script of ancient India, as represented by Ashoka as a simple vertical line in his Edicts of Ashoka in c. The most common representative glyph used in the modern Western world for the number 1 is the Arabic numeral, a vertical line, often with a serif at the top and sometimes a short horizontal line at the bottom.

One is neither a prime number nor a composite number, but a unit, like -1 and, in the Gaussian integers, i and -i. One is often the internal Spin boss representation of the Boolean constant true in computer systems. Because of the multiplicative identity, if f(x) is a multiplicative function, then f(1) must equal 1. In Principia Mathematica, 1 is defined as the set of all singletons. Culturally, people generally recognize that strength derives from unity and weakness is a product of disunity.

In German, the serif at the top may be extended into a long upstroke as long as the vertical line. In modern typefaces, the shape of the character for the digit 1 is typically typeset as a lining figure with an ascender, such that the digit is the same height and width as a capital letter. These symbols directly represent the concept of 'one' without breaking it down into phonetic components. Other common numeral prefixes for the number 1 include uni- (e.g., unicycle, universe, unicorn), sol- (e.g., solo dance), derived from Latin, or mono- (e.g., monorail, monogamy, monopoly) derived from Greek. 1 is the value of Legendre's constant, introduced in 1808 by Adrien-Marie Legendre to express the asymptotic behavior of the prime-counting function.
