49
What are some long-term risks of untreated kidney disease?
Both glomerular disease and chronic kidney stones can lead to renal failure and may require dialysis or a kidney transplant.
50
How do diabetes and hypertension contribute to kidney diseases?
Diabetes and hypertension are major risk factors for both glomerular disease and kidney stones.
51
What is renal replacement therapy?
Dialysis (hemodialysis or peritoneal dialysis) is required when kidney function declines.
52
What is Acute Kidney Injury (AKI)?
AKI is a rapid decline in kidney function leading to loss of homeostasis, fluid, electrolyte, and acid-base imbalances, and toxin build-up. It can be reversible if treated promptly.
## Footnote
AKI occurs within hours or a few days.
53
Who is most affected by Acute Kidney Injury (AKI)?
AKI mostly affects older adults, seen in up to 20% of people admitted to hospitals, and 65% of cases start in the community.
54
What is the mortality rate associated with untreated Acute Kidney Injury (AKI)?
The mortality rate for untreated AKI is between 30-70%, depending on age and comorbidities.
55
What are common risk factors for Acute Kidney Injury (AKI)?

56
How can Acute Kidney Injury (AKI) be managed?
Management of AKI depends on the type (pre-renal, intra-renal, post-renal) and is potentially reversible if the factors causing it are corrected.
57
What is Chronic Kidney Disease (CKD)?
CKD is defined as abnormalities in kidney function or structure present for more than 3 months, leading to a decline in glomerular filtration rate (GFR) (< 60 ml/min/1.73 m²) on at least two occasions separated by 90 days.

Caused by increased blood volume and the growing uterus compressing pelvic blood vessels
Symptoms include aching legs, swollen feet, muscle cramps, and a burning or throbbing sensation
## Footnote
Varicose veins are common and usually improve postpartum.
84

## Footnote
Hyperpigmentation is common, while stretch marks may fade after delivery.
86

## Footnote
These changes support the increased metabolic demands of pregnancy.
90
What is parturition (birth)?
Occurs around 280 days after the last menstrual period

What advice can be given to men (pre-conception) for optimal fertility?
Stop smoking
Reduce alcohol and caffeine intake
Maintain an ideal body weight
Exercise regularly
Eat a balanced diet
Avoid hot showers or tight underwear to maintain healthy testicular temperature
## Footnote
These lifestyle changes can improve male fertility.
95
What changes occur during the second trimester (Week 14-28)?
The easiest trimester due to decreasing hCG levels
Organogenesis continues, and the fetus grows
Ailments in this period are linked to rising progesterone and estrogen
Relaxin hormone helps with haemodynamic changes, increasing cardiac output and renal blood flow
## Footnote
This period is often marked by increased comfort for the mother.
96
What should you do to address nipple soreness or pain while breastfeeding?
Correct the baby’s latch.
## Footnote
Apply lanolin cream or breast milk to soothe the nipple. Let nipples air dry and avoid harsh soaps.
97

* Consider lactation-boosting foods and consult a lactation specialist.
## Footnote
None
98

* Express small amounts for comfort.
* Use laid-back nursing positions to slow the flow.
## Footnote
None
99
What are the benefits of breastfeeding for an infant?
Provides all necessary nutrients for the first six months.
* No additional food or fluids needed during the first six months.
* Linked to lower risks of asthma, diabetes, and obesity in the long term.
## Footnote
None
100
What is formula milk made from, and what are the different types?
Formula milk is usually made from processed, skimmed cow’s milk with added vitamins, fatty acids, and prebiotics.
* Whey-based formula is easier to digest, recommended for newborns.
* Casein-based formula is for hungrier babies but has no proven benefits for sleep or fullness.
## Footnote
None
101
What are the advantages and disadvantages of bottle-feeding?
Advantages: A strong bond can form between the baby and the feeder; formula contains essential vitamins like vitamin K.
* Disadvantages: Risk of incorrect formula preparation, bottles and teats require cleaning and sterilizing, switching back to breastfeeding can be challenging, and formula feeding can be expensive.
## Footnote
None
102
How do cervical mucus changes help with contraception?
Cervical mucus changes due to fluctuating hormone levels.
* At peak oestrogen levels, mucus becomes thin, stretchy, and alkaline, which helps sperm entry.
* After ovulation, progesterone thickens the mucus to block sperm.
## Footnote
None
103
What is the significance of body temperature changes in contraception?
Progesterone causes a 0.5°C temperature rise after ovulation, maintained until the end of the cycle.
* Natural family planning involves tracking temperature and cervical mucus for fertility periods.
## Footnote
None
104
What is the effectiveness of Natural Family Planning?
Up to 99% effective when followed correctly.

* Method Failure: Pregnancy occurs despite proper use of the contraceptive method.
## Footnote
None
109
What is the mechanism of action of combined hormonal contraceptives?
Oestrogen and progestin prevent ovulation, alter cervical mucus, and modify the endometrium to prevent implantation.
* They suppress the release of gonadotropins (FSH and LH), preventing ovulation.
