[Post-COVID Fatigue] Fatigue and Frequent Colds After COVID-19: What to Check First During Recovery

  • Key points
  • Ulsan When seeking consultation for post-COVID fatigue and immunity, the first step is not to jump to the conclusion that “your immune system has weakened,” but rather to determine how long the fatigue has persisted after the infection and to identify any accompanying symptoms, such as shortness of breath, chest pain, palpitations, or dizziness.
  • While fatigue and difficulty concentrating may persist after COVID-19, if you experience severe shortness of breath, chest pain, fainting, or new neurological symptoms, prompt medical evaluation is essential.
  • There are people who, even after their fever and cough have subsided following a bout with COVID-19, still feel that “their energy hasn’t returned,” “even the slightest exertion leaves them exhausted until the next day,” or “they seem to catch colds more easily.”

[Digestive System] If You Experience Recurring Nausea and Gagging, Check Your Autonomic Nervous System as Well

If you experience weight loss, repeated vomiting, vomiting blood, black stools, severe abdominal pain, dehydration, or new neurological symptoms, prompt medical evaluation is essential.
  • Some people experience an upset stomach when they wake up in the morning, feel the urge to retch before important events, and postpone meals because even a small amount of food makes them feel nauseous.

[Endometrial Adhesions] If Your Menstrual Flow Has Decreased and You’re Having Trouble Getting Pregnant, Here’s What to Check First

  • Endometrial adhesions refer to a condition in which the inner walls of the uterus stick together, which can affect the shape of the uterine cavity or the flow of menstrual blood.
  • If your menstrual flow has noticeably decreased or stopped following a D&C after a miscarriage, uterine surgery, or an intrauterine infection, or if you are experiencing recurrent miscarriages or difficulty conceiving, you should consult an OB/GYN to determine whether an evaluation of the uterine cavity is necessary.
  • It can be concerning if your menstrual flow decreases significantly compared to before after a miscarriage or childbirth, or if you experience lower abdominal pain around your expected period but have almost no bleeding.

[ boyak (tonic herbal medicine) ] If you feel tired no matter how much you sleep, it’s a sign that you may be suffering from chronic fatigue and should seek consultation at boyak (tonic herbal medicine)

  • If chronic fatigue is treated solely as a matter of boosting energy, the relief won’t last.
  • We need to assess your sleep, digestion, autonomic nervous system, any abnormalities in your blood test results, and when your physical strength began to decline, and then determine why your body is currently having difficulty recovering.
  • “No matter how much I sleep, I still feel tired.” “My test results are fine, but I feel sluggish and can’t concentrate.” This is what frustrates people suffering from chronic fatigue the most.

[ boyak (tonic herbal medicine) ] If you catch colds frequently and take a long time to recover, you should consider both a weakened immune system and boyak (tonic herbal medicine)

  • Ulsan Immune boyak (tonic herbal medicine) is not a “medicine that absolutely prevents you from catching a cold,” but rather a treatment that examines the underlying physical conditions that cause frequent colds and slow recovery.
  • If you experience frequent colds, a persistent cough, fatigue, loss of appetite, sleep disturbances, sweating, cold hands and feet, and poor digestion, you should not focus solely on your immune system but also assess your overall physical strength and recovery capacity.
  • Anyone can catch a cold.

[ boyak (tonic herbal medicine) ] Chronic Fatigue and Lethargy That Don’t Go Away Even After Rest: It’s Time to Reevaluate Your Recovery Ability

  • Ulsan When consulting on chronic fatigue and lethargy, it is important to determine whether the fatigue stems from “lack of sleep,” “inability to generate energy despite eating,” or “inability to recover from stress.”
  • Even if your blood test results show no major abnormalities, a combination of poor sleep quality, digestive issues, autonomic nervous system stress, menstrual or menopausal changes, and decreased physical stamina can leave you feeling sluggish and unmotivated all day long.
  • If you consistently feel like you haven’t woken up refreshed in the morning and your body doesn’t recover even after resting, your entire life can fall apart.
