Hot flashes
Sudden heat and sweating episodes are often linked to menopause, but new or severe symptoms require other causes to be ruled out.
Hot flashes are sudden episodes of heat, skin flushing, sweating and sometimes palpitations. They are most often linked to the menopausal transition, when estrogen levels and the sensitivity of the hypothalamic thermoregulation center change.
How They Feel
An episode may last from seconds to several minutes. Some people experience them rarely, while others have sleep disruption, fatigue, anxiety and irritability. Night sweats matter because poor sleep can worsen appetite, recovery and weight control.
What Can Trigger Them
Alcohol, spicy food, heat, stress, poor sleep, hot drinks and some medicines can worsen hot flashes. Similar heat sensations may occur with infections, thyroid disease, glucose swings, panic attacks and other conditions, so new or unusual symptoms should not be explained by menopause alone.
Keto And LCHF
A low-carb diet may help weight and glucose control, but it is not a stand-alone treatment for hot flashes. Avoid an overly severe deficit, and pay attention to salt, magnesium, protein, sleep and fat tolerance. Severe night sweats, unexplained weight loss, fever, chest pain or marked palpitations need medical assessment.
