A

Teriparatide is used for bone building in severe cases, and bisphosphonates continue to maintain bone density.

91
Q

A

Tailored treatments address specific risks, such as prevention in early menopause, maintenance in middle-age, and active treatment for advanced osteoporosis.

92

What is the role of ultra-low-dose estradiol + dydrogesterone therapy?

A

It provides symptom relief with minimal side effects, suitable for sensitive patients.

128
Q

What causes a hot flash during menopause?

A

A hot flash occurs when the hypothalamus mistakenly perceives an elevated body temperature and triggers cooling mechanisms, often due to hormonal changes.

129
Q

Which brain region regulates core body temperature during a hot flash?

A

The hypothalamus regulates core body temperature and is responsible for the false overheating signal during a hot flash.

130
Q

What happens to blood vessels during a hot flash?

A

Blood vessels near the skin dilate, increasing blood flow to promote heat dissipation, causing redness and warmth.

131
Q

Which body areas typically feel hot during a hot flash?

A

The chest, neck, and face often feel hot as blood flow increases to these areas.

132
Q

What role do sweat glands play during a hot flash?

A

Sweat glands release perspiration to cool the body through evaporation.

133
Q

How long does a typical hot flash episode last?

A

A hot flash usually lasts 2-5 minutes before the body temperature normalizes.

134
Q

What is the thermoneutral zone, and how does it change in menopausal women?

A

The thermoneutral zone is the temperature range where the body neither sweats nor shivers. In menopausal women, this range narrows, making them more sensitive to slight temperature changes.

135
Q

What hormone disruption is associated with hot flashes?

A

Declining estrogen levels during menopause disrupt the hypothalamus’s regulation of body temperature.

136
Q

How can hot flashes impact quality of life?

A

Hot flashes can disrupt daily activities and sleep, causing fatigue and irritability.

137
Q

What lifestyle changes can help manage hot flashes?

A

Wearing breathable clothing, keeping rooms cool, and avoiding triggers like caffeine, alcohol, and spicy foods can help manage hot flashes.

138
Q

What medical treatments are available for hot flashes?

A

Hormone therapy (HT) and non-hormonal treatments like SSRIs or SNRIs can reduce the frequency and severity of hot flashes.

139
Q

Why does the skin flush during a hot flash?

A

The skin flushes as blood vessels dilate to release heat, causing redness and warmth in the upper body.

140
Q

What occurs during the cooling phase of a hot flash?

A

The brain corrects its error, core body temperature normalizes, and the episode ends, often leaving the individual feeling damp or sweaty.

141
Q

How does declining estrogen affect the hypothalamus during menopause?

A

Declining estrogen disrupts the hypothalamus’s temperature regulation, leading to false overheating signals.
