Living with a rare chronic disease such as phenylketonuria (PKU) can be very stressful. Being limited to a strict diet also could make you feel isolated and alone. The abnormal levels of phenylalanine and tyrosine in the brain of PKU patients may also lower the levels of dopamine, a neurotransmitter that plays a role in reward processing.
All these factors may contribute to feelings of depression. Research has shown that almost 20% of patients with PKU may experience some form of depression.
Loss of interest
If you find you are no longer interested in things that used to bring you enjoyment, such as hobbies or social activities, then you may be experiencing depression.
Changes in weight or appetite
Depression and stress can cause sudden increases or decreases in your weight. Some people respond to stress by eating more, while others tend to lose their appetite
Feelings of despair or hopelessness
If you feel hopeless and like there is nothing you can do to ever make things better, this could be a warning sign of depression.
Depression can also lead to sharp changes in mood. Your temper may be shorter than usual, and small things may set you off unexpectedly and out of proportion to the severity of the trigger. Restlessness and frequent agitation are other signs of depression.
Some people with depression, though, have a distinct lack of emotion. You may not experience happiness or sadness, just a general numbness.
Changes in sleep
Depression can lead to changes in your sleep as well. Some people experience it as insomnia, while others experience it as oversleeping and having trouble getting out of bed.
Trouble concentrating, remembering things, and making decisions are common signs of depression. They may also be signs of other issues such as lack of sleep or even dehydration.
New aches or pains
Sometimes depression can manifest as new aches or pains in the body such as unexpected back pain or headaches.
Changes in energy levels and loss of motivation
You may notice you lack energy. Feelings of fatigue and sluggishness can make your body feel heavy and make tasks take longer. It may also be hard to motivate yourself to do even simple activities such as preparing a meal.
Guilt or self-loathing
People with depression also frequently have feelings of worthlessness. You may be overly critical of your appearance, actions, or perceived faults.
One of the most serious signs of depression is thoughts about death and suicide. If you are having suicidal thoughts or know someone who may be suicidal, seek professional help as soon as possible. The National Suicide Hotline is available 24 hours a day to provide phone, text, or chat assistance in the U.S. The International Association for Suicide Prevention provides contact information to help patients in numerous European countries.
