Increased appetite?


My friend (female) has recently experienced a significant increase in her appetite, almost eating two lunch boxes at each meal.
This is unusual for her, and she claims she doesn't know why she feels constantly hungry and gets hungry quickly.
During this period, she has had her menstrual cycle, but she mentions that she has never experienced this before.
She is quite tall, around 172 cm, and not overweight.
However, this excessive eating over the past week or two has caused her to gain 5 kg.
Additionally, her menstrual cycle has been very irregular; sometimes it comes once a month, and during her period, she eats ice cream without experiencing any menstrual pain, which she has never had.
What could be causing her binge eating? If she needs to go to the hospital for an examination, which department should she consult?

Hello: The reasons for increased appetite, binge eating, and weight gain include pregnancy, endocrine disorders (such as diabetes and thyroid dysfunction), and psychological issues.
You may consult a family medicine specialist or a general internist.

More Info


Increased appetite, especially when it is sudden and unexplained, can be concerning and may indicate an underlying health issue. Your friend's situation, characterized by a significant increase in food intake, rapid weight gain, and irregular menstrual cycles, warrants careful consideration and possibly a medical evaluation.

There are several potential causes for increased appetite, including hormonal changes, metabolic disorders, psychological factors, and certain medical conditions. Given that your friend has experienced irregular menstrual cycles, it is essential to consider the possibility of hormonal imbalances. Conditions such as polycystic ovary syndrome (PCOS) can lead to increased appetite and weight gain, along with menstrual irregularities. PCOS is characterized by hormonal imbalances that can affect ovulation and lead to symptoms such as irregular periods, weight gain, and increased appetite.

Another possibility is that your friend may be experiencing stress or emotional factors that could contribute to her eating behavior. Emotional eating is a common response to stress, anxiety, or changes in mood, and it can lead to increased food intake and weight gain. If your friend has been under significant stress or experiencing emotional challenges, this could be a contributing factor to her increased appetite.

Additionally, certain medical conditions, such as hyperthyroidism, can lead to increased appetite and weight changes. Hyperthyroidism occurs when the thyroid gland is overactive, leading to an increase in metabolism and appetite. Other conditions, such as diabetes mellitus, can also cause increased hunger, particularly if blood sugar levels are not well controlled.

Given these possibilities, it is advisable for your friend to seek medical attention. A visit to a gastroenterologist may be appropriate, as they can evaluate her digestive health and appetite changes. However, considering the potential hormonal and metabolic factors, it may also be beneficial for her to consult with an endocrinologist, who specializes in hormonal disorders. This specialist can assess her menstrual irregularities and any potential hormonal imbalances.

During the medical evaluation, the healthcare provider may conduct a thorough history and physical examination, including blood tests to assess hormone levels, thyroid function, and glucose metabolism. Depending on the findings, further investigations such as imaging studies or referrals to other specialists may be warranted.

In summary, your friend's increased appetite and associated symptoms could stem from various factors, including hormonal imbalances, psychological influences, or underlying medical conditions. It is crucial for her to seek medical advice to determine the underlying cause and receive appropriate treatment. Encouraging her to make an appointment with a gastroenterologist or endocrinologist would be a prudent step in addressing her concerns and promoting her overall health.
