Hi Doctors, I am a 27M single. About 5 months ago, my family noticed changes in my nails, and a physician confirmed nail clubbing. I underwent investigations including 2D Echo with Doppler, HRCT chest, ESR, hemogram, T3, T4, TSH, and LFT, and all reports were normal. The doctor mentioned it could be genetic as major causes were ruled out. On reviewing my old photos, my nails appeared normal until around 2016–2017. Mild changes began around 2018, progressed by 2020, and became more prominent by 2023, with further noticeable changes up to now. I also have external hemorrhoids since around 2020, along with mild constipation and a feeling of incomplete bowel emptying, which improves with a high-fiber diet. Could there be any underlying condition linking these issues, or can hemorrhoids/constipation contribute to nail clubbing? Do I need any further evaluation, or can this be considered benign? I am also  also feeling quite depressed due to the cosmetic changes.
