Rapid weight loss, no matter how much I eat, I still lose weight..?

My friend has recently been experiencing a strange condition where he has bowel movements half an hour after eating, sometimes going 1 to 2 times after a single meal.
In just two weeks, he has lost weight from 53 kg to 47 kg.
He also feels a sense of fullness even when not eating and has been unusually sleepy.
What could be wrong with him?

More Info

Your friend's situation is concerning and warrants immediate attention. Rapid weight loss, especially in the context of gastrointestinal symptoms such as frequent bowel movements and a sense of fullness after eating very little, can indicate several underlying health issues. Here are some potential explanations for your friend's symptoms:
1. Gastrointestinal Disorders: Conditions such as Irritable Bowel Syndrome (IBS), inflammatory bowel disease (IBD), or infections can lead to increased bowel movements and diarrhea. These conditions can disrupt normal digestion and absorption of nutrients, leading to weight loss.

2. Malabsorption Issues: If the body is unable to absorb nutrients properly due to conditions like celiac disease or pancreatic insufficiency, it can result in weight loss despite adequate food intake. Symptoms may include diarrhea, bloating, and abdominal pain.

3. Hyperthyroidism: An overactive thyroid can accelerate metabolism, leading to rapid weight loss, increased appetite, and changes in bowel habits. Symptoms may also include fatigue, irritability, and sleep disturbances.

4. Psychological Factors: Stress, anxiety, or depression can significantly affect eating habits and digestion. Some individuals may experience a loss of appetite or changes in their digestive patterns when under emotional distress.

5. Infections: Gastroenteritis or other infections can cause diarrhea and weight loss. If your friend has been exposed to contaminated food or water, this could explain the sudden onset of symptoms.

6. Eating Disorders: Conditions like anorexia nervosa or bulimia can lead to drastic weight loss and altered eating patterns. If your friend is experiencing a distorted body image or unhealthy relationships with food, this could be a serious concern.

7. Medication Side Effects: If your friend has recently started any new medications, it's essential to consider that some drugs can cause gastrointestinal side effects, including diarrhea and changes in appetite.

Given these possibilities, it is crucial for your friend to seek medical attention as soon as possible. A healthcare professional can conduct a thorough evaluation, including a physical examination, medical history, and possibly laboratory tests or imaging studies, to determine the underlying cause of these symptoms.
In the meantime, encourage your friend to stay hydrated, especially if they are experiencing diarrhea, as this can lead to dehydration. They should also keep a record of their symptoms, including any dietary changes, stressors, or other relevant factors, to provide their healthcare provider with comprehensive information.

In summary, while rapid weight loss can sometimes be a result of lifestyle changes or temporary conditions, the combination of symptoms your friend is experiencing suggests a need for professional evaluation. Early intervention can help address any underlying issues and prevent further complications.
