I don't understand how anyone can think they've only gone 3 days without food when it's actually 3 weeks. You need serious medical intervention. Ask for an appointment with your GP. Tell them it's urgent. You're going to make yourself very ill.
A quick google search brought up this.
Going three weeks without food can lead to significant health issues, including muscle wasting, weakened immune system, and potentially life-threatening complications. While the body can technically survive for a while without food, the prolonged lack of nutrients can lead to severe health consequences.
Here's a more detailed look at what could happen:
Muscle Loss:
The body will start using muscle tissue for energy when it runs out of stored fat.
Weakened Immune System:
Starvation can compromise the immune system, making you more susceptible to infections.
Brain Function Impairment:
Brain function can be affected, leading to difficulties with concentration, memory, and even potential psychotic episodes.
Gastrointestinal Issues:
The digestive system can be disrupted, leading to nausea, vomiting, and constipation.
Other Complications:
You might experience hair loss, lower sex drive, and cold intolerance, among other things.
Refeeding Syndrome:
If food is reintroduced too quickly after a long period of starvation, it can cause a dangerous and potentially life-threatening complication called refeeding syndrome. This involves a rapid shift in electrolytes and can lead to breathing difficulties, seizures, and even cardiac arrest,
